Wow that is strange. There are two admin folders with the Xcgal 2.0.2 version. In my download there was, a admin folder and then an admin v1.1 folder. I only uploaded the plain admin folder with my upload. Not sure if that could be it or not.
You could try downloading the module again from a different mirror and then upload the admin directory again overwriting files and update the module and system.
Be sure to back up your site first!
