When trying to back up MechWarrior 4 I keep running into the same issue. When I try to run the patch, it tells me "wrong file size". I have followed all the instructions for the NO-Cd install, but I keep getting the same thing. I have unsafedisced the MW4 file. It was 336 kbs, now its 3.33Mbs. Can someone please Help???? thanks in advance!!!!
