Hi,
Please feel free to contact us at any time by clicking the "Contact Us" button at the top of The3dStudio.com and we'll get back to you as fast as we can.
As for FTP, we actually don't allow it into our datacenter because of the security risks it would bring into our datacenter and servers. Instead, we have a very nice web based uploader that will easily let you upload many (hundreds to thousands) of files at one time. Give it a shot, it's very fast and easy to use.
If you have a lot of files (5000 or more) please contact us and we can offer other options like sending us a DVD/hard drive of your files if needed.
