Welcome to the forums!
First let me stress that I'm not Comodo staff, just a volunteer moderator.
It does seem a bit strange that geekbuddy provides this clean-up batch on mediafire.com.
I have downloaded and analyzed it and it seems to be a batch file that cleans left-overs from a CIS install.
But I'm pretty sure that's not going to fix your issue.
I'll give someone a note about the hosting on mediafire of this, they have plenty of space on their own server-farms.
Regarding your license for CIS Pro, for how long should that have been valid?
I know the 30day license starts complaining after 15 days that it will start to expire.
Can you check the More, About if it shows anything about your registration?
