This is what I read in the display since 5mins. My KPA crashes very often, b.t.w. but it booted by itself everytime...Is there any way, to initialize from this point? Or do I have to send it back...? It´s not even a week at my place... 
Cheers for your help,

upss, Try switching off and then reboot keeping "System" pressed... did you upgraded to the last FW version?

Had the same problem and got rid of it.
I made a fault when I put files in the folders of the usb stick. I had some cab files in the download folder of my PC (Win7) that already had been copied to the cab folder of USB stick and had been installed days before.
Yesterday when I copied the files of my download folder from the PC to the stick, I took them once again and copied them to the rig folder of the usb.
This caused the assertion failed message and the system crashed and needed a reboot. Assertion came again every time I tried to browse over the wrong rigs.
I don't know wheter it was wrong that the files been double now or that cab files been stored in the wrong rig folder.
Solved like this: Made a restore from a backup that I had made to my stick when I got the KPA new.
(Made many tries and searched for the trick, wich now you don't need to repeat)
Then I deleted the wrong cab/rig-files and importet everything else again.
System stable again!
Maybe your problem is of the same kind.
Good luck!
Thanks Frosch (denke mal, du bist Kartoffel wie ich:)
This is exactly the way, it happened to me!
Unfortunately I was not patient enough - so, I´ve sent it back today to get a brand-new one. But I´ll know how to act in the future, if this failure should ever come to past again. The KPA is way too awesome to give it up..!
Thanks for your help!
As soon as the new one arrived at my place, I will profile my Hughes & Kettner Statesman Dual 6L6, which sounds incredible with tone bones triodes/Class A just cranked clean channel.
Keep on rocking, guys!!
Greets,

Klar
Leute, im moment ist noch English angesagt! 
OK, Kartoffelmode off.
To come back to the OT.
One more thing:
There have been some uploads of corrupted profiles,
EVH-files and AFD-files.
They have been uploaded once again and work now.
Good to know, this might be the reason...(?)!
I received the shipping confirmation for the new KPA today. So, from top:) And a one...and a two...and a three...
