Comodo AV Not Updating

Every time i try to update or even scan my computer, i get this…

Which version do you currently have installed?

5.0.163652.1142

What happens when you run the diagnostics?

If running them doesn’t help then I’d advise reinstalling it by following the methods I’ve outlined here.
