Actually that solution didn't work for me.
I followed the same instructions as piotrparfeniuk, got the exact same behaviour. This was on a Win2K8R2 SP1 (and then once more for luck on a Win2K8R2 without the SP1). The server is a VMware VM on ESX4. The SQL server is an off-box SQL2005 which appears to be working normally - and it certainly serving other DBs successfully.
If I switch off SSL I get the exact same error as piotrparfeniuk. If I switch on SSL (which I think is how things are supposed to be set up?) it looks like this.
If I ignore the error and attempt to click the yellow * for New Payload, the page throws an error:

Turning off UAC makes no difference. Running IE (IE8) as Administrator makes no difference. Reinstalling Silverlight (4.0.60831.0) makes no difference. Accessing the console via a remote browser makes no difference.
The problem here is that I'm on a short deadline (the project is to use Mobile Management to roll out managed iPads) and I can't get this part of the software to work at all.
Is there any sure fire way to get this to work? Any particular OS, patch level, etc? I can easily blow away my dev environment and start again, but I've done that three times so far and have got nowhere.
I freely admit that IIS, Silverlight and server certificates are not my forte, and I would really appreciate some guidance from someone more clueful than myself.
Help?
