I tried to install the newest patch (I never loaded the old one) and in the process it told me that my Poser.rsr was corrupt and therefore update wouldn't occur. Then, of course I went to see if I could run P4 and I couldn't. Then what I did was copy the entire directory to another partition, delete the old directory, and reinstall P4 fresh. Then I installed the patch and everything seems to work. Now I want to copy over the relevant files from the copy I made without corrupting P4 or the patch. I checked the readme file and it doesn't list the files that the patch replaces. Can anyone tell me which P4 and Patch files not to overwrite?

If you copy them all over you will be prompted if there is a file duplication, select the latest version each time.
