I think my issue is with gibbed tools. I was getting errors sometimes, but it was extracting files. I didn't realize that the files were corrupted. I'm getting the error described here http://www.saintsrowmods.com/forum/...saintsrow3-unpackstr2-exe-keeps-crashing.558/
However, I have tried v59,60, and 61 with the same results
Just to make sure it's gibbed tools that are a problem download the attached file, decompress it and see if you can unpack the ui_legal_pc.cpeg_pc file. If it unpacks OK then gibbed tools is your problem. If so try downloading the Gentlemen of Steelport mod and use the version of the tools included in the mod files.
EDIT: Removed test file as problem resolved
