Thanks for your answers... It's the simplest things you forget to try :-)
Now it works, after this steps.
1. Moved my dlc folder to d:\ 2. Changed "Rocksmith Installation Directory" in settings to d:\ 3. Did a rename of all my dlc/cdlc 4. Put dlc folder back to it's original place 5. Changed "Rocksmith Installation Directory" back 6. Tried to do another rename of all files and it works, no error message.
I can even do longer filenames and directories without any problems now then before, this is strange but I'm not complaining :-)
Sorry to say that it´s back after I bought some dlc´s on steam sale this weekend, bought the volbeat ones. same as before and some new ones (that worked before without problem) with a dot (.) after the Artis and/or Album, like W.A.S.P. and R.E.M. and Garage Inc. that creates one path with the dot and one without. Is there a way to completely remove app´s all files to start over totally fresh?
UPDATE/FIX: Moved the songs that I had problems with out of the dlc folder did a rescan and then moved the files back to the root of the dlc folder and did another rescan and now it works again.
