Hopefully someone has an idea what could be wrong, so here comes my problem

.
i wanted to give SH5 another try, so i put up a new modlist.
First i patched the .exe with TDW patcher. Then i used JSGME to enable some mods from sobers mod list (correct order).
At this stage i wanted to test if anythings going well....
For testing i started (as always) the single mission in Narvik where ur about to sink the "warspite" (i dont know the english name of this mission).
Everything looked good but then i made the mistake? to use TC 4x and got a CTD. On another test i got a CTD after firing a torpedo.
When i disable all mods (only running patched exe) everythings ok. But with a few mods enabled there are random CTDs....
My rig: i73930K, 16GB RAM, Nvidia GTX570, 256GB SSD (SH5 installed there)
