Q: Aperture not working after update.

Hello,

  I just updated to OS 10.7.5 and also updated to Aperture ver. 3.4 (auto-updater) and now Aperture won't open, it just crashes.  I tried reinstalling, but it didn't help.  Another app. Canon EOS Utility also stopped working, I also reinstalled this to no avail.  I was using both of these programs yesturday with no problems.

Can Anyone help with this?

  Thanks in advance.
