Not catching downloads from IE9

hey guys,

When i click on a download link from megauploadforum.net the link redirects to a php encryption page, to megaupload.com and then it opens the IE download popup not the download studio application.

I've been through all settings in both downloadstudio and IE9 but have failed to see why this doesn't work.

I'm sure I've had this working before I had to rebuild the machine after a hdd failure, however I cant remeber what i did to get it working before. :(

any ideas?

Many thanks
