IL-2 1946 SAS modact ultrapack uninstall?

[HARDLYDANK]

I have IL-2 1946 from steam and i installed the sas ultrapack but I can't get it working and I'm trying to uninstall it. I deleted the file for the mod and have searched in the game files for all files related to it and deleted them. However, the game starts with the ultrapack startup screen, but then it goes away and it stops launching. I tried reinstalling the game, backing up files, running an older version of the game, nothing will work. Any help would be appreciated. Thanks!
