My aperture keeps crashing after a recent transfer of pics from card reader

Question

running 10.7.2 and Aperture version 3.2.2.  Recently was transferring files from an Memorystick pro duo in a card reader (which has been done many times before).  Everything seemed to transfer fine and i ejected the card.  That's when the trouble started.  I haven't been able to run Aperture since.  The program opens up, then says it is "procesing" after being open for several seconds.  Then it crashes and shuts down and an error message comes up.  Don't know what to do and would hate to lose many pics!!  Help please!!!!!  First part of error message is copied below (let me know if more of it is needed):

Answer 1

Will it be a problem if i uninstall/reinstall Aperture?  I shouldn't lose my photo database, correct?
No, reinstallation will not affect your database.
I haven't tried with a Guest account, is it really worth trying?
I suggested that, to narrow down the source of the trouble.  The usual reasons for crashing are:
A corrupted Aperture database
A newly imported corrupted image inside your database
Inconsistent Preference settings
Insufficient permissions to access parts of your database
Wrong formatting of the dirive containing the Aperture Library
Network problems, if the library or masters are on a network volume
Insufficient memory or hard disk
Incompatible Aperture plug-ins
Incompatible frameworks in the system library (may be cause by installing third party apps, most often Final cut or other multi media software)
A problem with the Aperture Apllication itself
A problem with the OS
Broken hardware
User error
If your error message is so unspecific, it may be looking for a needle in a hay stack to find clues.
If Aperture does not crash when working from a different account (not necessarily the guest account  - any other new account you create for yourself for testing purposes will do) then the reasons 5-12 will be unlikely, since those are system wide problems. Then you should try to fix your library and preferences.
If on the other hand it even crashes working from a different account, I'd suggest to reinstall Aperture or reinstall Lion, since the problem is not tied to your account.
If other applications are acting up, too, I'd recommend to run a hardware test and to repair your system volume.
To fix Preferences and Library, see here:
Aperture 3: Troubleshooting Basics: http://support.apple.com/kb/HT3805
I did try that eventually and while it allowed me to access Aperture after i completed that, once i closed it and opened it the next time it began crashing again like before.
Since you already did repair your library, try rebuilding next and removing the Aperture Preference file and presets, as described in the trouble shooting basics. After a crash it is really a good idea to rebuild the library and recreate the preferences, since crashing and/or force quitting can leave those inconsistent.
If you can work after repairing, but then Aperture crashes again, this looks very much like a single, defective image inside your library. Do you remember the projects you imported recently? The next time you start Aperture, I'd defer the generation of Previews. Press the Shift key immediately after you start Aperture to prevent preview generation for that session. Then inspect carefully your most recent imports.
