Connection error: proxy 500 error detected

########URGENT HELP NEEDED!###########

My VPS on my single node is down.
I can't start it because of the error I get in the interface: Error: connection error 500: proxy loop detected

I cant start it from the prompt because I get:
Container config file does not exist

I did find a configfile at: /etc/pve/nodes/Debian-70-wheezy-64-minimal/openvz/103.conf
When I tried to copy it to /etc.vz/conf I got:

root@3 /etc/pve/nodes/Debian-70-wheezy-64-minimal/openvz # cp 103.conf /etc/vz/conf/
cp: cannot create regular file `/etc/vz/conf/103.conf': File exists

But /etc/vz/conf/ is empty.
Hope someone can help!
Would pay fo a solution!
