No Description - Modify Backup Maintenance Plan failes to save.

Hello,

SS2k5 - 9.00.3050 (x64) - Most current SP

I've created a backup maintenance plan 'All User Databases'.  Plan saved and executes.

Modify plan to add new subplan step to remove old backup files, save fails with a Studio Dialog encapsulating the message  ->  No Description

Cannot save the Maintenance Plan.

Any ideas about how to save the Plan?

Thank You...  Covi
