So I still can't get AU manager to stop looking for BFD and it's 4 elements, it keeps going into a loop asking me for the valid file,mwhich is not there of course. I have trashed the AU cache file. Gone into logic au manager and de-selected the 4 BFD elements and it still wants to scan them when I run logic. I can't re install BFD cos I have not got the disk space.
There are no BFD files left on the machine that I can find, how do I stop the AU manager looking for them?
That's what you *did* do - however, you *did not* do the specific steps I said in my post above, which will fix your problem.
