Update failure, error 106

I am using Comodo firewall since few weeks. Its, version 2.1.1.1.
For the last few days i am unable to update it. When I try to update I receive this message,

Error:106, could not complete update process.

Any idea what is the problem?
Should I reinstall or repair it?

Hi,

A reinstall may help. If not you may want to email support@comodo.com

It is a problem at the registry. Another member had the same problem after deleting some registry entries. Do you use a registry cleaner?

Thanks for replys. Now it is OK, I think was some temporary error.
