remote desktop issue

I have installed the concurrent rdp hack to allow multiple concurrent sessions.

I am having a serious issue with rdp - if I rdp into my machine from another machine, it works the first time. But then if i log in at the machine itself - it hangs on the logging in screen and never gets in. In addition if I then try to login from the other machine again I get an error that the rdp server is busy. Nothing I do gets me in until i do a hard reboot of the machine

any tips on this?

nothing in the event viewer about this except for the hard reboot.

I and several others are having this same issue.
