Remove (delete) the files from Comodo server (already backuped)

I’ve tried to activate my Comodo Online account without success with the beta version.
I need to turn back to version 1.7.312.
It’s really a leak of features compared, for instance, with Mozy.
I want to further translate version 3, but I need my account working first (posted elsewhere in the forum).

By now, is there any way to remove my files from Comodo server? (i.e., the ones already backuped)

Any news?

Any news about the translation?

Lack of support?
