Cant Deauthorize Other Machines

Wondered if anyone can help, problems pretty obvious from the title, i can’t login to Corona as it’s saying i need to deauthorize it on the other machines its installed on, the problem… those machines have been blitzed and so i cant actually do it. Looked in my account on here and can’t see anything to deauthorize anything, any help would be greatly appreciated. 

I’ve deauthed you.
