There's two files, SCFLicenseLog and SCFLicenseSignature-DO NOT MODIFY OR DELETE.

I've already tried repairing sketchup via sketchup unistaller, but it didn't seem to do anything.

would this help?

Hi. I've tinkered with my computer profile a bit, and ended up destroying my original profile. I had to use a recover program to repair the profile.
After that, my fredo license wouldn't work with the sketchucation message showing "error A04". I repaired sketchup, but the problem wasn't solved. I even went ahead and bought a second license for the same plug-in, but it still said I had to revalidate. How do I revalidate my license in this situation?
