As a further suggestion, as Microsoft would charge if you opened a problem, post to a Microsoft newsgroup. An MS person might be willing to open a problem for free if you can clearly state the problem, the analysis and have a database backup so they can investigate the problem. As space management changes are captured in the transaction log, a pre-condition backup and all of the transaction log backups until the problem occurred would be ideal.

To post, recommend using http://www.developersdex.com/sql/default.asp?p=580 as this site has a cleaner interface than the MS interface.

Cheers
