I've had this same problem develop on other scores I've working on. I can only save my work if I do a manual save and dictate exactly where I want the files to go. If I do an AutoSave, it can't find the file destination.
Now, its doing that same issue whenever I do the manual save.
The error is " Copy Error 2"
to C:\Users\Tom\AppData\temp\FIN3B86.tmp\presets\1 preset
It looks the FIN611C and FI3B86, whatever that means, could be the issue. Any clues as to how to remedy this?
