Opensuse 11 Rc1 Main Oss Repo Error

Hi, I recently installed OpenSuse 11 rc1 from Gnome Live cd, 64bit, and the repository refresh gave the following error:

Downloading repository 'Main Repository (OSS)' metadata [error]
Repository 'Main Repository (OSS)' is invalid.
/var/cache/zypp/raw/http:__download.opensuse.org_distribution_11.0_rep o_oss__12mZrVL: No metadata checksums in content file.
Please check if the URIs defined for this repository are pointing to a valid repository.
Skipping repository 'Main Repository (OSS)' because of the above error.
Some of the repositories have not been refreshed because of an error.

So, practicaly I have no OSS repo, what should I do with it?

Thank you in anticipation!
