Can't see v.X Package folder on Desktop

Running PowerPoint v.X with Service Release 1 (Office Update 10.1.5) and OS X 10.3.4 on a Dual-USB iBook. A PowerPoint Package saved to the administrator's Desktop now does not appear on the Desktop or in the Desktop Finder window or in a Finder window search, even though I can still open it from list of recent files under the PowerPoint File menu. I have restarted and have repaired permissions, but to no avail. Suggestions on how I can make this folder visible again? Thanks.
