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.

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?

@TIG
I did what Rich-O-Brien said, running th repair as administrator, with the sketchup closed. But nothing's changed. It keeps showing B03 when I first click on "activate license", and A04 when I apply my license file, which is in my "C:-users-profile name-desktop" route.

Has it got to do with me recently changing the PC's name? I've been using the rubies for a while before I changed my desktop's name in the windows system setting.

@TIG
I tried uninstalling and reinstalling sketchup, but it seems like I should try again with deleting every sketchup-related files I can get my hands on. Maybe then I should try as you suggested.

On the other hand, is a pop-up window saying "B03" also an error?

It still says the signature file is absent. Is there something wrong with the folder I saved my licenses?
