Desactivation and Reset error(recurring error message)

My two computers got virus and I reset Windows, so I couldn't desactivate the codes directly from the computers.

When I tried to desactive the codes, a following error occurs 

"An error has occurred with your offline-deactivation. If you continue to have problems, please Please log a support request."

So I tried to reset the codes, similar error occurs.

"An error has occurred

An email has been sent to support to inform them of the error.

Please try reloading / refreshing this page."

How can I get two new codes? Thanks in advacne
