Ok, dCreateGame Exceeded occurs when the d2jsp module doesn't report game created with in dCreateGame milliseconds. Your problem isn't a problem with the GUI. It's a problem with loading d2jsp. I know that this didn't solve your problem, but it should make solving it easier for someone who's more experienced with d2jsp related errors than I am.
Edit: Either that or the GUI isn't loading the loader. To see if this is the case, go into a game and run loader.exe, it should print some text to screan saying "d2jsp by njaguar loaded" or something.
