So I just recently reinstalled the GOG versions of BG1 and 2 and installed the Tutu mod and the Widescreen mod, and now when I launch the game through tutu, it crashes about 15 seconds after launching every time (usually around the start of character creation or loading a save). When I play vanilla BG it doesn't crash, and when I play BG2 it doesn't crash - it just seems to be with EasyTutu.

I'm using Unfinished Business v13, Font Mod 2.1, Widescreen 3.05, and EasyTutu_ToB

New to this troubleshooting thing on the forums, any additional information I need to post? Thanks!

Post your weidu.log for the TuTu install here. Also, you cannot use previously saved games with the widescreen mod, unless you converted them at install time.

Yeah, it was a completely fresh install, so no save files were to be had.

The widescreen mod needs to be installed last, because it alters game assets.

Thanks for that little tidbit of knowledge, and I also think it was Avast DeepScreen terminating my processes without asking for permission.
