Transfer Queue is Stuck

I am unable to transfer files from one server to another. It worked fine on my trial version, but now that I have bought the software, the transfers aren't wokring. The transfer queue is stuck. The file never goes anywhere or else it may look like it has been transferred, but the file length is 0 bytes.

Are you sure your FTP servers support server-to-server (FXP) transfers?

Yes, a fellow teammmeber has been using SmartFTP successfully on the exact same servers. In fact, I had to ask him to make my transfers for me since mine kept getting stuck in the queue. He had no problem at all
