Updated Windows 10 - No my CIS 10 won't open [tried reinstall]

Having a bit of a nightmare. I got an email from comodo to update my CIS before my windows update, I did so, waited some time then updated my windows. I’ve had another recent windows update and now I can no longer open CIS.

Task bar says its running, but I can’t get it to fully open. An occasionally get a diagnostic report due to an error.

Has this happened to other people or just me. Ive tried reinstalling with no success.

regards, ste
