If you CTD like that She-Wolf, it usually means a mis-match of the vessel versus what is in the Rec Manual. If you happen to shoot at that particular target without usinig the Rec Manual, as soon as the torpedoes get to the "EXPLOSION!!!" point, you'll CTD also. I'd say you've probably got some mod soup of the bad kind, not like what Bleiente mixed-up with his mod, which is very handsome looking all-around, btw, and probably plays a pinch tougher than TMO, or at least, if you do stupid things like I did, and attack a well-defended tanker at 1000 hours with a dead-calm sea...
If you used JSGME and had done a "Snapshot" of the game files, and you're at "Stock" now, check your game files. Also, be sure that you do NOT play a saved game or mission from another mod. Your "My Documents / SH4" folder may well need to be deleted, so that when you play the game again and it creates a new one, it's empty and only has info from the "Stock" game in it. That may well be where your issue is, but the "Snapshot" feature of JSGME can really be useful to help diagnose. Also, if I haven't already mentioned it, be sure and check out
Rocking Robbins SH4CRS utility. I don't think I can say enough good things about it. It ~really~ comes in handy when you've got a lot of mod versions to deal with...
Don't forget about the use of
MultiSH to help you, if you have the hard drive space, to have multiple SH4 installs, and a separate save folder for each.
