I think stringy had this once, told him to remove all his .tmp files and have a clear out of pk3 files he has downloaded from lots of servers, soundpacks, skins watermarks etc from his etmain folder. That worked for him. When running et in vista make sure he has an administrator account or right click the et icon on his desktop and run as administrator to allow the game full access. If still not working go to the et exe file inside the wolfenstein folder, right click, properties, compatibility and click run this program as windows xp service pack 2 mode. Make sure he is running 2.60b. Make sure pb is up to date, run the pbweb.exe in the pb folder.
