Somewhat similar issue here. Upgraded to the latest OS (and Rig Manager) from the Beta versions. My Performance Bank #1 got corrupted as a result. All but one rig of the 5 was missing, replaced with the standard "Crunch" rig. Looking at the Profiler with Rig Manager, Rig Manager shows the correct "names" of the slots in the performance, but the rig itself was still "Crunch". Tried repairing everything with Rig Manager for that Performance Bank and could not do so. I reloaded each of the slots with the correct rig, and saved everything. But once I disconnected Rig Manager and restarted the profiler, that performance bank reverted back to the corrupted state. After trying several more times, I gave up and used an empty Performance bank to create a new performance and then moved that up the list to position 1. I erased the old Performance Bank 1.
Everything appears to be working now.
