Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Hi legendreturn and welcome to W7 Forums

Just to clarify what you've said. You have 2 PCs connected via the same router. The game runs on one machine, but not the other. Is this still the case?

It could well be that your copy of the game (which I presume you have had to activate/register) is tied to the first machine it is installed on and will only run on that machine.

Sometimes, these errors are not actually errors on your part, and there is nothing you can do except wait for the site to sort them out at their end, as this can indicate that they're having problems with their database or whatever.

I would try to see if it runs on the PC you said it ran previously first.

First of all ,thanks for reply and helping me

Just to clarify what you've said. You have 2 PCs connected via the same router. The game runs on one machine, but not the other. Is this still the case?

You understand right
And i am already runnning the game right now on the other pc and working perfect

I have 2 accounts for the game for each machine

also tried 3 different accounts on the pc which have the problem

It could well be that your copy of the game (which I presume you have had to activate/register) is tied to the first machine it is installed on and will only run on that machine.

But i still don't understand why the game running on only one machine ???

Sometimes, these errors are not actually errors on your part, and there is nothing you can do except wait for the site to sort them out at their end, as this can indicate that they're having problems with their database or whatever.

May be you are right (but i am not sure)

Just want to know,is there any possiblity that the problem is from the router
or from the mac adress?

Also,is there any possiblity that the company of my internet can do something to fix this ???

Or the biggest possiblity is from site+database (as you said?)

Thanks for reading ....

 

[Stevy22]

is there any Manual proxy address added by your organization on your internet, like a Lock-down network or something??

If you're currently running the game with no problems on one machine, then that eliminates that machine, the router, and the site itself from the equation. The only other thing left is your other machine. Since that also connects via the same router, and can presumably browse the net with no problems, that rules out issues such as NIC drivers. However, it does not rule out a corrupt browser. Try http://www.sevenforums.com/tutorials/1222-internet-explorer-reset.html to see if it helps. If not, then it could be that the game license is tied to the first machine, probably by its MAC address, in which case this won't work.

I don't understand it
But if you mean that the site may be in lock down from my internet only,
then you are wrong because as i said: i am currently running the game on one machine perfect and no problems at all


Thanks for sharing your idea

I don't know what you mean by "NIC drivers",also i am sure that is not from ther borwser (because i tried it on 3 different widnows + different versions of IE)

May be it will work if change the MAC adress (because in the first of the error it is talking about the mac adress)
However,i don't know how to change the MAC adress and i don't know if i changed it the net will wrok proberly or not

REALLY THANKS VERY MUCH FOR HELPING ME
