3.10 Update – wpsc-update

Installed 3.10.0 update. Link for wpsc-update returns “You do not have sufficient permissions to access this page” I am the Admin with full access rights. Store is still fine but Store Settings tabs do not load in place – must open them in in browser tabs. Please advise on solution or get me back to prior rev. Thanks
