Re-Install not working


I have recently purchased Smart FTP v3.01020.2 And it has been working great for a few months. I have now bought a new computer and am trying to upload it to my new computer. It seems to have installed properly as all the FTP's are visible but I cannot transfer files back and forth. They sit in the que and nothing happens. I am having to use my old computer as it works fine in there until this issue is resolved. I have re-installed the Smart FTP v3.01020.2 at least three times on my new computer and the same issue exists each time. Please let me know how to fix this.
