Hope this is posted in the right place, cant find the old question posts??

Ok so I haven't loaded rocksmith up in a while,

It was working but all my song data was gone so I reverted back to last save . 

Now I get a white loading screen and rocksmith shuts down.

I noticed the save was from September though could this be the issue I tried  going back to the up to date save from today but still wont start.

I have broke something .

Think I fixed it seems I went back to that dodgy update from September. 

How did you fix it?  Mine was working a couple of days ago and just won't boot now?

His issue was the update from Sept.

in order to fix that issue you need the new D3DX9.dll:

if you haven't played since or was the first time you played since Sept, that maybe the issue, assuming you are using a PC.
