DonnaOB,
Boy, I haven't heard about this one for a while. You might want to read the following post which I compiled back in September, http://social.technet.microsoft.com/Forums/ar/projectprofessional2010general/thread/2f4f6838-4e76-42eb-8166-c7fea80f3a54.
As far as I know, no one ever came up with a definitive solution. However since I haven't seen any recent posts on this issue, it may in fact have been resolved by the latest updates to Project 2010 AND Office 2010. Go to, http://technet.microsoft.com/en-us/office/ee748587,
and insure that you have the latest updates installed. Ignore the "guidance" that indicates the updates are for the server version of Project. Updates listed apply to all versions of Project.
Hope this helps.
John
