After Upgrade to 9.0.1 : Plesk and Drwebd fails

[Raichu]

I upgraded to Plesk 9.0.1 and got the email of success. When i try to login to plesk, connection fails. At the same time my user stopped receiving emails. I went and restarted PSA and this is what i got:

Starting xinetd service... done
Starting named service... done
Starting mysqld service... done
Starting postgresql service... done
Starting psa-spamassassin service... done
Plesk: Starting Mail Server... already started
Starting Plesk... failed
Starting drwebd service... failed

I looked at the logs and it stated Plesk failed due to missing key. I check the directory where the keys are located and its all there plus the key backup made my psa. dr. webd is failing because plesk wont start ...

Any ideas?
