Gwaythiel -
I wanted the same thing, since the 1.01.012 patched version will not run on my computer. I was able to run release version 1.00 just fine (purchased from Best Buy). The patched version crashes my computer with a Runtime Error. After reading the forums there is no rhyme or reason.
I uninstalled and went back to the 1.0 version for the meantime.
I've got the same problem
