Downgrade to Plesk 8.0.0?

[awillys]

Hi,

Just upgrade my Plesk 8.0.0 to Plesk 8.0.1 and result is that the Control Panel seems to be broken now as I am stuck to the page where it asks for my Preferences, Default IP Address and Shared IP addresses. There i keep pressing the "ok"button but it just keeps bringing me back to the same page :/

Any idea why?
and is it safe to remove and reinstall Plesk? without breaking the websites?

config:
1and1 dedicated server
FC4

Note: i sent an email to 1and1 tech support but as they usually reply 1 week later i would be gratefull if someone as a better option.

Regards,
Antonio
