I had this happen to me all of the sudden last eve several times, forcing me to shut down. The Profiler and Remote are new purchased in July and I updated the Spring Reverb Beta OS and latest firmware.
I was playing for about an hour with no issues when all of the sudden the remote went dark. After 3 reboot attempts where the Remote lit up for a second then went dark again, I was finally able to boot, but once I went into an effect setting in Performance mode and attempted to change an effect value such as delay time, the unit started changing rigs!
I unplugged everything, then realized my cell phone was laying on top of the unit! I move it away from the Kemper, unplugged for a minute and rebooted. Was fine for an hour pf playing and fiddling after that. I do remember one other time I had to reboot and I think the cell phone was on top in that instance as well. I will definitely keep an eye on this and am a bit nervous since I have a show this weekend. Hopefully that was the issue!
