Can't reset the "my pending files" list

I had to uninstall and then reinstall Comodo Firewall v3, but can not open the Pending files lists, that states 44 files waiting for review.
Every time I click on the “waiting for your review” link or go to the Defense+ section and click ·My pending files" link, the computer freezes and never recovers.
I suppose some registry key had been damaged somehow.
Thanks for the answer.
