Blackscreen and then error with lib/os.pyc. By deleting logo1,logo2 and ymir (before and after the update launcher do its job) nothing happens. It doesnīt work because they download again (automatically) before launching the game on the screen.
Now Iīm going to uninstall and install again to see what happens. I think itīs my Windows 8.1 that is trolling me because It works perfectly on my notebook with Windows 7 :S
Edit: After uninstall it I just copied/pasted the entire folder of the game from my notebook (where it worked) to my pc and now it works. (No need to download the game from the web and install)
