i recently ugraded from 9.0.4 to 9.0.1, but now when i try to open programs, they don't run, it says that filesa re missing..i tried burning the additional smi files to upgrade to a higher version but when i copied to the mac it copied them as bin files, is there any way that i can undo the changes through restore, or how can i burn the smi files on a windows pc to use on the mac? any help is appreciated, thanks.
