Error Message 'Failed to save document'

Hello,

I have a part that reliably gives the error 'Failed tosavedocument'  when trying to save. The file is in SW2006formatand I have tried using the conversion wizard.

Has anyone else seen this error with similar reliability?Cananyone try saving this document on their machine to 2007?We'vetried that here but all of our machines are twins and itdidn'twork.

The file is attached to this post.

Thanks!
