Can you please explain to me exactly what you did???? It might be the problem I am having, what's this "administrator mode?" When I installed CEP it wouldn't let me change the files in the FIFA 11 folder because it was on "read only." I couldn't change that so I went into properties and and the securities tab and set it so that my user had permission to modify the files, etc. I installed everything correctly and ran the regenerator, but I noticed that the folder still says it's on read-only, but I'm not sure if that means anything since I was able to extract the files to that folder. Probably doesn't have anything to do with it but thought I'd make sure and throw it out there.
Again, after it didn't work the first time, I uninstalled FIFA, deleted all its files, then re-installed it, installed the 1.01 patch, made the FIFA 11 folder on not read only (giving John, the user, permission to modify the files, etc.), extracted the files, ran the 1.6 regenerator, and it still crashes to the desktop. I get a flickering right at the beginning (Kaka screen, when I first tried it and had run it with the 1.5 it did this, but when I ran the regen again and then downloaded and ran the 1.6 regenerator, it didn't give me a flicker. This try around, I get the flicker), and then at the Iniesta screen with the league logos it crashes to the desktop.
I ran the regenerator again, and this time (was the first time ever, didn't do this the first time around) when it crashed I got a Microsoft Windows window that popped up saying FIFA 11 stopped working properly. I'm a bit confused now, and I wonder if it has something to do with this read-only stuff. I doubt it though because if it truly were on read only, wouldn't the regenerator not work at all?
Edit: and by the way, I have Vista. Apparently the Regenerator hasn't been tested on Vista. Should I try a different regenerator? Where can I find one?
