I broke down and bought a copy of SH4 Gold Edition DVD a year ago, just to shelve my original DVD SH4 version 1.0 because I was tired of fooling around with the Direct2Drive "upgrade" of the U-Boat Missions that brought the game up to version 1.5.
What's the best way of checking if SecuROM is running on your system? Would it show up in the registey?
I'm like aanker, I never use the gu.exe "shortcut" to start my game. I always go directly to my Silent Hunter Wolves of the Pacific folder and use the sh4.exe icon file to start the game. There are two .exe files for starting the game, I only use the sh4.exe file.
