1. What is your "A:" drive?
2. Did you create the rest of the path yourself?
3. Are you attempting to start from the Steam menu?
4. Are you starting Wolves of the Pacific, or U-Boat Missions?

Copying the "not-missing" files will not solve the problem. If you are seeing the FotRSU splash screen, then the mod structure in the MODS folder should be good. Windows could still be attempting to interfere with the activation. It would leave the graphic files alone, but rollback ini & cfg files.

If you are copying the Steam SH4 files from one folder to another without having first run the game to initialize its licensing, you can run into issues, but if that copy of the game runs find with FotRSU removed, then the licensing is fine. Just be sure you are invoking the proper short-cut for the SH4.exe file. Another possible issue is that the game is a WinXP game, and it might be seeing the "A:" drive as a 3 1/2" floppy, and not whatever it is that you have. I doubt it has that ability, but you never know... If the Stock version there runs fine without FotRSU though, that is probably not an issue.

One last thing I can think of for you to look at is: When doing the Large Address Aware, you have to make certain that the SH4.exe "target" is write-enabled. In the SH4 game folder, right-click the SH4.exe file, and choose "Properties" from the bottom of the context menu. The first "General" tab page has the "Attributes" section at the bottom, and you want to be sure that the tick-box for "Read-only" is cleared. Then run LAA or the 4Gig Patch after that. While you generally won't see the errors you are getting, it does crash the game as it enters the 3D world if SH4.exe is not able to write to a larger memory space.
