Powerrack is not remembering performance settings.

Hi Kemper Owners,

Since the release of the new rig manager/editor I have been experiencing a strange problem. I edit performances and add effects to them etc and everything is fine. But after a while of not using the Kemper, I switch on and the settings on my performances are not like I left them before, ie: where I had a clean sound progged, it now has an amp on it with distortion, or when I progged a lead guitar setting with a delay or reverb, they are missing, and the amp sound I had is changed to something else. I backed up the performances before I switched off the last time, but even when I load them again from the backup they do not load like when I previously saved them. It's extremely annoying, I have had this happen 3 times now, is there some kind of internal battery that needs changing or am I missing something else?

Thanks in advance....

Software is all up to date. I'll try again:

I create a performance, edit it, ie: add effects like reverb/delay/chorus what ever, say on bank 1, then I move to bank 2 and create a 2nd one there, ie: a clean sound without distortion etc, maybe with some reverb and chorus. all good, continue on to the other banks doing the same. Save it as store it. A week later I switch on, load that performance and the bank 1 or two etc has not been stored like I saved it, ie: the clean sound will now have an amp on it with distortion, or the delay and reverb are not there anymore, as if I never stored/saved it, it has happened 3 times now, even if I load the performance fro my desktop where I backed it up, the Profiler does not give me those settings I saved/backed up.

Thanks Burkhard, I am positive I have tried both, I will try again tonight and post results...
