I didn't have your problem with the M260 but had many others. Sergio in Elation support sent me the firmware [Version 1.07] and I reflashed the unit. It fixed some of the problems, but not all. See this post:
http://forums.elationlighting....36491/m/740008011001Before it went out on you, have you experienced a lot of bugs with your M260?
BTW: Your question really belongs in the Elation forum.
