User Guide URL goes to a blank page

I’m new to CDE… When I follow the link for the “User Guide” from Disk Encryption – Comodo Free Disk Encryption Software to Comodo Help, I get a (mostly) blank page with the text:

‘invalid operation’

has the documentation moved elsewhere?

I cannot find anything in the online help. I tried accessing the CDE user guide from Comodo Help and then looking for CDE in the Select product at the top. It was not there.

Hi Eddie and Eric. Does this link help for now, seeing the help link is invalid. Kind regards.
