Rocksmith does not start

[Nithrash]

Hi, today Rocksmith is not wanted more start, as soon as I started closes immediately after you open the window, from that moment he no longer wanted to learn from, I even deleted the game and downloaded again by steam, but continues to do the same problem!

But heck what the hell happens every time in this game! Do you know a fix to solve?

Thanks in advance guys.

Which platform?

PC steam

Until recently worked great

I solved ... or simply unplugged a USB key and the game immediately after has started ...

Weird bug ...
