Help! iPhoto keeps crashing when I try to export photos

Question

I'm working on a MacBook Pro (about 3 years old), and recently updated to Mountain Lion and iPhoto 9.  Aside from opening iPhoto9 to confirm that my photo library was there, I didn't "use" the software until this morning.
I uploaded photos from my camera (via USB cable), edited them, dropped them into an album, then clicked "Export" with the intent of exporting them to my Shutterfly account.  However, iPhoto abruptly closed and I got the following error message:
"iPhoto quit unexpectedly while using the HPPhotoExport plug-in."
I re-opened iPhoto to find that the photos I had uploaded did not show up in the album I had created, or my library, or under "events", and I'm not sure where else they could be.  I reconnected my camera to re-upload the photos, and iPhoto recognized the photos I had previously uploaded as having been uploaded already.  I selected them to upload them again.  Edited them again.  Dropped them back into the same album.  Tried to export again and got the same result. 
Any ideas on what the issue might be???  Thanks!!

Upgrade to v9.4.1 or
Trash the HP Plug in from /Library/Application Support/iPhoto
There are two libraries where this plugin might be
HD/ Library
and
HD/Users/Your Name / Library
(On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
