Problem with TeamEditor 3.5

Hello guys, I haven't played GP4 for some weeks and now I returned, but for some reason TeamEditor is not running fine anymore. Onve I click on the icon TeamEditor asks me to choose the GP4 folder first. After I have chosen the folder or the wad (doesn't matter for the problem) and clicked "Ok", TeamEditor asks me to choose the GP4 folder first again. So we can say it's a problem with TeamEditor isn't starting anymore. I will try a fresh installation tomorrow, but maybe someone has another idea what might cause this problem as well. Thank you!

I have changed the compatibility mod of TeamEditor to Windows XP Service Pack 3 and now it works fine. Thanks!
