I don't like talking on forums, but I'll chime in Joce. I got mine at fw5.08. It would reset 000 to EMPTY anytime I organized a lot of cabs in axeiii-edit. After fw6.04 update, 000 started resetting at any random time. I eventually said f*** it and left 000 EMPTY. 2 days later, the preset was back. It hasn't reset since. I've been in email exchange with Ian off and on. They know about the issue. I don't know if anyone can figure out what's causing it. Try leaving 000 empty for a few days. Or try the system reset like Effulgent recommends.
