Just a quick question.

I had the Creation Kit running on the Windows 8 consumer preview fine, a few crashes but I expected that on a preview OS.
I then bought and installed the full version of Windows 8 Pro, re-installed Steam, along with Skyrim and the construction kit.
Skyrim runs fine, But when I come to try and run the creation kit, the Steam box opens saying "Preparing to launch blah blah"
but nothing happens. No errors, no indication that it's even trying to do anything.

I don't know how to fix this. I've uninstalled and then re-installed it a number of times, checked the cache but it says that everything should be working.
Please help if you've had similar problems or just know how to fix it!

Thank you! (First time poster)
