In that automatic response should be a ticket number and a link to check the status of the ticket.
Since you sent it on Staurday, then two of the 4 days it has sat in the in box for support, because MTU does not work on weekends. Depending on how many tickets are submitted over the weekend then 2 days is not really a lengthy time. If they haven't responded by the end of the week, then let me know and I will check on it.
If you had uninstalled it before reformatting the drive, then you would have been able to re-install imediately afterward. MTU has changed all their programs to allow you to un-install it on-line and re-install it on a different computer (or reformated one which is recognized as a different computer. So yes if possible always un-install any MTU programs before you make changes to a computer, either physical components or operating system (not including upgrades).
