Zombie thread but Ill reply on the off chance OP sees. I broke my left extreme metacarpal years ago and for over 20 years have lived with a metal plate in my left hand. I know your pinky pain. I initially would practice a bit and stop wjen my pinky hurt, after discovering RS last year I began playing longer and longer, barres hurt for me as well as anything requiring pinky dexterity. After a few weeks of playing till it hurt I noticed 3 things, the first being I could play longer before my pinky began to hurt, second dexterity in my pinky had improved, third was that overall movement in my pinky read everyday use and flexibility in my pinky have been improving more than the physical therapy they had me doing.
Run Steam as Admin validate files start Rocksmith exit out of Rocksmith and then Steam, run as normal user. See if that fixes the issue. With each new Windows release more and more user isolation occurs even if your account is admin typically it's not full admin.
Run steam as admin one time. Even if your account has admin privies, right click run as admin. Start rs2014 then exit rs, should work under normal acct perms after.
Make sure you have the latest dll, large red banner top of this page, make sure its in the proper folder and is named correctly and there is no other dll by the same name in there. If there is delete it, start rs, go into learn a song, then back out of rs, place the dll in the folder you should be good to go.
Got SlaterTot8 sorted even gave him a quick rundown of using the beta toolkit cli to convert so he avoids the 100% bug. @@NatureBoyBrad delete that dll and the ones in your downloads folder and redownload from the red banner up top.
