Can someone help.

I've just downloaded UniUploader, running the latest Roster, .NET all up to date etc. I have ensured that I have the correct Admin password.

However I'm unsure what to enter into the URL.

I have tried the URL that is given when I click the upload profile button, but all I get is the BADREQUESTSTREAM error.

The UTR I am trying is http://pagansofdawn.dragonmountain.co.u ... date&a=g:1

I've also tried

http://pagansofdawn.dragonmountain.co.u ... p?p=update

Can anyone help me.

Did you go over the basic setup for Uniuploader?
MediaWiki/UniUploader:BasicSetup

I did and I finally spotted the issue, my Firewall was blocking the outgoing traffic. As soon as I let the firewall know to trust the application it ran like a dream.

lol, that would do it
Glad you got it working!
