Help with FreshWDL on new webspace

Back home now and it still will not work. Reverted to standard FTP but this did not help. After the STOR commands it just sits till it times out.
The things that have changed since FTP last worked:-

  1. I upgraded WD directly from 10.37R build 70 to 10.37S build 90 (because I read that this was necessary for FreshWDL to work properly)
    2.I have changed to webspace on a new server. Brian can upload to the new one and my relative (the administrator of the server) installed WD and uploaded successfully as well.

I have gone over and over settings and can find nothing wrong. Apart from log in details they should be the same as when it last worked.
What else could be wrong?
Is it possible for settings files to be corrupted or messed up in some way?
I’m really scratching my head here?
