I went back onto Rig Manager recently and all of my stored profiles have gone.
By stored I mean I created separate folders for clean, Distorted, Bass profiles etc and kept any profiles that I didn't want on my profiler in these files till I needed them.
Two things I've done recently that may be part of the problem, I updated my profiler and Rig Manager recently and when I logged into Rig Manager, Rig Manager said the authors name was different on my profiler and would I like it to match the author name on Rig Manager.
I agreed to change it but none of my files showed up, so I changed both the profiler and Rig Manager back to my full name and nothing showed again.
