How to create a fully isolated full conversion

[SaraWaffle]

Your Computer, I am in desperate need f your help!!
I followed your direction the best I could.
Okay, so far, when I start up the batch file, everything works. However, when it asks me to make a profile in the menu screen, it will not allow me to do so. So basically, I cannot play my mod at all. When I hit the 'X' in the corner of the Profile box, the game crashes and gives me an error.
PLEASE HELP MEE!!!
