Problems with Java?

[Nicholas Flamel]

ok so I've got this Java Application called GametableDnD that iv'e been useing to play Dungeons and Dragons online wiht my sister and some freinds for about a year now. Just recently I've moved over from a computer running on vista to my new computer that runs on 64 bit windows 7 home primium and I haven't been able to get the application to run.

I thought maybe I downloaded the wrong java so Iv'e tried 32 bit java, 64 bit java, and both on the same computer. the 32 bit doesn't work at all and the 64 bit jave gives me a message saying it can't find the main class when ever I try to runt h aplication. But it has to have a main class, because it works just fine for every one else and iv'e tried reinstalling both java and the application multiple times.

I'm bafflled, computer science and electrical engineering majors I know are baffled, and best buy's geek squad was useless, so I thought I'd come here and ask for advice before paying someone to fix it for me. I'm Pre-med and don't have much time to socialize so this DnD game is very important to me, if someone can help me solve this problem I'll be extremely grateful.

If you haven't already tried, run the game in compatibility mode.

Right Click Game > Properties > Compatibility > Check Box, Select Vista from the drop down.

ok I right clicked the file and went to properties but there wasn't even a place to click for compatibility options. I feel I should mention that the file it's self isn't so so much the game as the tools you need to play the play the game. (it's a .jar file if that makes any difference.

It probably requires a specific version of the JRE (java runtime environment.) Try this one, remove the current version you have installed first. Download Java 2 Platform, Standard Edition, v 1.4.2 (J2SE)

Ok the link you posted took me to a page that said that version reached the end of it's service term,and had a bunch of links to 'read more" but none that took you to a download.

Ok and I finled out the sytems specs to the best of my abilities, but I mean I'm a total n00b when it comes to computers so I may have just no t know where to look to find the information.

Ok I trie downloading the different version of Java like you said, but when I did my computer just sat there like "what am I supposed to do with this" the sameway it did when i downlloaded the 32 bit Jre instead of the 64 bit one.
