I recently downloaded JA2 and installed it, and every time I quit the game it crashes (Windows explains that it crashed and asks to send an error report). While this isn't a terrible problem, it's a still a problem with the game. Has anyone else experienced this, and if so, is there a solution?

Ah, so it is. Thanks for the link, Wolfox

You're welcome. BTW, would you please mark the answer as a solution? That will close this question.
Thanks and enjoy the game... I know I am enjoying it. ;-)

When I exit I get this problem, but I have no cursor to click okay. [Enter] doesn't work either. I have to Ctrl-Alt-Del and open the task manager and kill it manually. Anyone else have this problem. Kind of a pain in my eyes. May not play this much because of it.
I hope they actually fix this.

Here is a copy of what I get that caused the problem. This is old but it is still not fixed and if I use my CD version it doesnt do it soooo it must be a GoG.com problem

Installed Jagged Alliance 2 yesterday (July 6,2012) on my PC with Windows 7. Everything is fine until I quit and then it crashes. Then, when I try to start it up again I receive an "Error loading save game" message and cannot continue the game. I have tried three different save game slots - to no avail.

You've installed the game in Program Files. See here for more info on what to do.
