Hmmm... that D:\Users \Username folder, is that something you created, or did you move your Documents folders etc off of your C: drive? Windows does protect folders in what it considers "system" folders, such as Program Files folders, but it had been known to put its sticky fingers in other folders, such as My Documents... but not everyone's computer is like that. What kind of cpu and how much RAM do you have in your computer? Do you know what level your User Access Control (UAC) is set to? Are you playing other mods in another SH4 install? If you right-click on your SH4.exe file in the game folder, then left-click on Properties, on the first "General" tab, there is a "Read-only" tick box. Is that clear or have a check mark in it?
