When I woke up this morning and TURNED on the computer, I got a blue screen (not a BSOD) saying "Please wait...". After it finished doing something, I logged on and an error appeared with the FOLLOWING text:

ERROR: Could not load C:\program files\comodo\firewall\cfpres.dll. Please check if application installation folder has this file. Aborting application.

Anyone know what the problem is?

I use Windows XP SP2.

Thank you.Oh, and because of this problem, I cannot reinstall.Do you have the latest version of CFP installed?
Do you by any chance have Avast installed? There are some people who report issues with CFP when Avast is installed.I have the latest version of CFP installed. I don't use Avast!You say you can't reinstall... can you uninstall?
If you can I would suggest you do that, delete the Comodo folder if the uninstaller doesn't do it for you, CLEAN up any temp files and REGISTRY keys with CCleaner and try to install again.While searching through the Comodo forums, I FOUND the solution.
Right now Defense+ is learning, so that's a good sign that it is working.

Anyway, thank you for your reply.Great you got it working again.
Could you post the solution here or at least link it? You never know when someone with the same problem comes along.OK, here is the link:

Not exactly what the problem was, but at least it works.
