Problem with pleskrestore in new installation

[infocasa]

Hi,

Due to hardware failure we had to install a new server with intention of restoring the last backup done but we keep getting errors when restoring.
The new server is a fresh Fedora Core 6 x86_64 with Plesk 8.1 installed with the autoinstaller. The server is a dual Xeon supermicro with 2GB RAM and an Adaptec based RAID subsystem. OS runs just fine and Plesk installation went smoothly.

Command we run:

/usr/local/psa/bin/pleskrestore --restore backup_file -level all -map plesk-map

The error we get is the following:

------------------------------------------------------------------------
Restore has been started
------------------------------------------------------------------------.
WARNING! Restore with "-level all" switch brings server to exactly the same
state, as was saved in backup file. All objects, not presented in the backup
file (clients or domains) will be deleted. Proceed? [yes/no]: yes

As suggested in other similar posts I checked that no were silly things in .bashrc, tried other shells and edited the previously created map file, no success.

I'll appreciate any advice or help.

Regards
