What is your TeamDrive username? You could buy the special offer which comes with 10 GB and then you could buy two additional licenses. The licenses are user-based. It doesn't matter who orders the licenses. What matters is who enters the licenses. Once you buy the licenses they are yours to administer. Whoever you give them to only has to enter the license key into their client. Again, licenses are user-based and each user can have multiple installations. The license key only needs to be entered once. When you receive your licenses there will be a number detailing how many users can enter the license key. If you are unable to make your purchase on the shop you can place an e-mail order with us and I can set everything up for you. We would just need your e-mail address, username, and a physical billing address.
I just searched for you in our system and it seems like you have an account setup to use the US servers. That's fine but the default settings in our shop for night are for users who are using EU servers. If you downloaded a TDUS client and created your account with that then your data is stored on a US server. You will have to place your order via e-mail.
