latest version crashes...

Just installed the latest version of the firewall this morning and get crashes like every 2 minutes after launching from the toolbar. I checked with grc and pcflank all rules/tests seem ok (stealthed well). I also get crashes right away after running cpfupdat.exe. (After the crash I still have the toolbar.)
I’ve got WinXP sp2. Other security products installed: PeerGuardian 2.0 Beta 6b, Avast antivirus v4.7 and Antihook 2.5.

The cryptic error I get from WinXP:
AppName: cpf.exe AppVer: ModName: unknown
ModVer: Offset: 65726966

Thanks in advance!
