Re-install the 1.0.4 from the USB key. Procedure described in the thread "Kemper is toast"

Same picture I had some hours before :-)

Got it work again.

First of all a disclaimer: I have no clue if the manufacturer likes it when users go to the maintanance menu. I would recommend not to touch anything where you feel unsure. I guess you could toast the unit that hard in there that you'd need to send it back to support. It's your own decision and your own responsibility when you do that.

And that's what I did:

Copied from Armins site:

Note: ALL the rigs will be erased during this procedure!!

• Switch the main knob to off
  
• Hold the left/top soft-key above the LCD
  
• while still holding this key - switch KPA to tuner
  
• Maintenance Module will be started
  
• In the 'Maintenance' menu goto 'Memory'
  
• Use Memory FormatFlash and InitFlash (I pressed init here)
  
• Check if the KPA works (booting, tuner)
  
• Resinstall your rigs - I recommend to just install the stock rigs - in case you have corruped rigs on your USB stick
  
• Load additional rigs - check if all rigs work (Did not work with FW 1.05, freezed again!)
  
• Check all the KPA settings

I then have put FW 1.04 back on the stick and downdated, then loaded my restored state and now I'm back FW 1.04.

I'll wait for now until someone can say why the update failed.

Hectrucci, please send that picture to support anyway.
Cool to see Armin's fix works for stuff like that.

Had same this morning and did send the photo to support.
I had to install the previous FW version.

I've got the same message yesterday twice. Got the KPA working again following Armin's fix. I know this fix by head now But when 1.05 was working it worked fine and the latency has improved IMHO. I've tweaked some sounds and off course made a back up. If I do a restore then I can't find the sounds I've tweaked, save as...(renamed) anymore. Another thing is that when I have assigned midi PC numbers these ore gone when doing a restore. Does this mean that if I make a new rig that back up isn't enough and I always have to export new rigs to be sure they are saved (including midi PC number)?

I only have freezes when I turn the KPA of and only starting up if freezes many times. If it works it works fine. I think a go back to 1.04......

What you can do instead of exporting rigs from the unit itself, using it's UI wich is timeconsuming is to extract the rigs from the backupfiles.
The shareware 'total commander' is a different kind of windows-explorer, with it you can look inside the backup-file wich is a zipped kind of archive and you can directly take out rigs and cabs by drag-and-drop.
Be careful and don't touch anything else, where you could corrupt global settings or midi settings. That could lead into another weird errors.

Okay thanks! I'll try that. I have total commander already installed so that's no problem. But I still hope there'll be very soon FW that doesn't crash anymore.......
