Well I get this popup after I installed The V1.10 update package: [ Missing License File: [ /!\ Your license file is missing. Would you like to browse for it? yes/no ] ] It's was very annoying to reinstall GSC2011(download version) on my updated pc, second install. First I had problems with AVG but solved. I created a map GSC2012 instead of GSC2012demo and it worked out to play the 2012 version. Then I installed the 'V1.10 update package' in the map gsc2012(what else) succesfully. After that I wanted to play and get the popup above. Ps, I also installed the V1.10 update package on GSC2012 when I had choosen for a map GSC2012demo but then it was still playable without the V1.10 update.
