Welcome to the forums, AL ~
Unfortunately, Windows' most recent updates seemed to really do a number on things, and CFP didn't do too well with all that.
Most folks have found that uninstalling CFP after there were conflicts with the updates having been installed, then reinstalling it, has resolved the problems for them.
If you choose this route, here's my recommendation (remember, the MS Updates are already installed):
1. Boot into SafeMode. Uninstall the FW.
2. Reboot into SafeMode. Run a registry cleaner like ccleaner or RegSeeker (being sure to use their "backup" feature prior to removing any entries.
3. Reboot into SafeMode. Reinstall the FW.
Note: If you have a lot of detailed Network Rules that you don't want to rebuild, you can export them from the registry prior to uninstalling the FW.
Open Regedit and navigate to:
HKLM/System/Software/Comodo/Firewall Pro, and then work your way through that to find the precise key for Network rules (I'm not sure the exact name of it, or I'd tell you - I'm running the latest Beta at the moment, and it's different). When you find it, highlight, select "Edit" menu, then "Export". Save it to the desktop or someplace easy to find.
Immediately after reinstalling the FW, but BEFORE rebooting, reimport that registry key by double-clicking it. Then when you reboot, your Network Monitor rules will be there already.
