Error when trying to open Sonic Generations - white error box

[GamerlanYT]

Hello everyone! I've a really big problem with this game. when i try to open it, it appears a white error box without any text (spanish version), i've read on the internet that in some cases it appears a error message too.

in any case, I want to know how to fix it. 6 month before it worked prefectly, but yesterday when i installed it again, that error appeared. I tried to reinsltall the game, but it was useless.

someone has te same problem? any ideas? solutions? thank you all for your help :)
