I've been playing Rocksmith 2014 fine for a year and had no problems until today. I was playing through my laptop but didn't notice it wasn't on charge and whilst playing the battery level went to 0 and so my laptop powered itself off whilst I was in the middle of a song. I rebooted the laptop and started Rocksmith again but 95% of the time it crashes somewhere between the press Enter welcome screen and the 'Learn a song, session mode... etc' menu. It crashes with 'Rocksmith2014.exe has stopped working' message. Any ideas? I dunno, is there some sort of cache I can clear or something that wasn't able to resolve itself when my laptop unexpectedly shut itself down? Thanks for any help.
