download manager not working properly

[faxtion]

I have a website on our development server, but the client has the exact same site (files/mySQL) on their server. But when I add a new item to the manager on the clients server it does not appear on the site, but I am able to make other files which are already there visible or not visible.
On the development site everything is working fine.

There is a difference between the servers, the development server is linux, and the client is using windows.

Here is the system information for the development server

Is anyone able to shed any light on this?

imho windoze servers suck, there is a chance the folder permissions aren't quite correct if you can't see images etc....

You need to upgrade to latest version of CMSMS as only the last 2 versions are supported...

Update on the situation:
I have got a copy of the site (the one on the windows server) and have it running locally on my MAMP install, and everything is working just fine. So I can assume it would mean there is something up with the windows set up, but I am not very clued up on server set ups.

Does anyone have any incline to what could be causing the issue?
