1) There was a small problem with the server which was limiting uploads to around 3MB, this has now been fixed.
2) The server is running Unix, so it is case sensitive. If you create a folder called PDF, it will give a 404 error if you type pdf in the URL.
3) The number on concurrent connections allowed per user has been increased from two to five.
Thanks Rik
Guess who found out the hard way. :)
