CSM Mod Problem

Hi everybody

I don't know why but when i launch mods with CSM, sometimes it blocks on a black screen just after the launch and before the start menu.
It's strange because i've this problem with some mods but not with all mods

For example, no soucy with Gp4league and 1985 mods, but its wrong with 1984 or 1996 ????

Try setting your GP4.exe to Compatibility Mode ---> Windows XP SP2.

it works, thanks
