Archive copied from xdrive is not valid or corrupted

Hi,

today I made a complete backup of my C: - drive. As backup files are more and
more growing I made ATI store it in a netdrive. The validation was ok.
Later I started a recovery of this archive to restore the complete old version of C: .
This operation (ca 30min) started ok but stalled with 34 seconds left.
After waiting for additional 30 minutes I switched the PC off.
(I guess at this point the network-driver was being corrupted due to restoring,
so the program couldn't contact the netdrive any more)
Now I'm trying to get up and running with a boot-CD.
Acronis runs fine, but the netdrive can't be found.
So I copied two archives to a neighbor-pc.
The files are found there but reported corrupt.

Just now I found out that the boot-CD had been created with ATI 7 and the files have been built with ATI 11 !

How can I get out of this trap?

Regards
Detlef
