Well after a new graphicscard driver was installed RS2014 wont boot up anymore, I get the white screen but the short black screen which initialize the game itself is missing instead it gets back to the desktop.

I tried now older Geforce driver and the internal drivers from windows but no can do anymore.

Is this a known problem with you guys or is it the first time you heard about it?

Never heard of it before.  Try the official forum.  Someone there might know.

Thanks for the link. Thought that Ubisoft didn't have forums.

Hello,

I have had this same issue after computer or system upgrades over the years and have reinstalled the game and was back in business. Before you do this back up your dlc folder so you can install your current dlc folder to your fresh install of the game. I hope this helps!!
