Hi Pat,
To judge from the details of Microsoft's security May bulletin, there were updates for MS Office 2007 and below, but none for Office 2010 (at the link below, choose "Affected Software and Download Locations", then "Microsoft Office Suites and Software"):

In addition, MS Office 2010 is indicated as non-affected by a vulnerability which affects previous versions of MS Office:

If you want to check whether you missed any updates, you can either run Windows Update (make sure that you have the option to receive updates for other Microsoft products activated), or you can try out this suggestion over here and update MS Office 2010 from within the program itself:
