Thank you for using our premium service. You can either order additional user licenses online, or make a deposit to your DriveHQ account and then email DriveHQ customer support. We can take care of it within less than 24 hours.
To make a deposit, please logon http://www.drivehq.com, click on My Account, then click on Deposit.
To order additional services, you can logon and click on My Account, then click on Subscribe. DriveHQ supports multiple orders, so you can order several subscription services at the same time. For example, you can order 100GB twice to make it 200GB. If you don't need multiple subscription services, please cancel the previously ordered service after you've upgraded it.
