Can't uninstall comodo

Comodo wont acces to inet, a message said “DNS_PROBE_FINISHED_NXDOMAIN”. So i try to make a clean uninstall/install, but I stuck on “Uninstall Feedback” windows, that wont show any option to pick for continue the uninstall process. I try update to new version but it said “unable to check for new version”.
Is there a way to fix this, or baypass the feedback window?
Im using winXP with comodo spanish, and i deactivate the Comodo Update on windows startup.

Recently there have been problems with Comodo’s Secure DNS servers. The error message may be about that. Can Dragon access the web now or is the problem persisting?

Both have been fixed. Tks
