-HELP- Error number 1 DSP-RAM failed on Kc

[pixie]

hi everyone,

I'm the not so happy owner of a Kc since yesterday.
I've just bought a virus Kc and I'm very disapointed.
Most of the time the virus works fine but I encounter a few stability issues (keyboard not responding or reboot)

I tried to update to OS V6.5 (currently OS V6.0) with no success.
The update process seems fine as midi sysex are transmitted and received, but when I press "store"in order to flash the OS I get :

Error number 1 DSP-RAM failed

I've searched different forums (including this one) and found at least 5 people having this issue on a Kc. No answers to this problem so far.

I've had tons of synths but this is my first Virus, so I'm a kinda noob.

Is my Kc deffective ?
Do I have to send it back to germany ? (I live in France)
I know there are a few Virus experts among you. Can anyone tell me what's going on with those Kc ?

thx for your answers...
regards

Frederic
