Avast for Linux - Not updating virus definitions

Hello,

I have Avast installed for Linux (avast4workstation_1.3.0-2_i386.deb) and it cannot update the virus definitions.

When i press the Update Database button I’m getting “Downloaded update is corrupted, try again.” permanently.

In console everything looks ok:

stc@USB-Kubuntu:~$ avast-update 
Checking for virus signature updates...
An update for /home/stc/.avast/400.vps is available.  Fetching update...
Update done: /home/stc/.avast/400.vps dated 2010-04-13 08:27 /home/stc/.avast/400.vps.
stc@USB-Kubuntu:~$    

After this command the file “400.vps.new 1,4KB” appears in the avast working directory.

… but GUI shows the old definitions version (dated 05.01.2009).

Any idea?
