I have had the Zune Software installed for a long time now and I’m pretty happy with it as a music player (used it before I got my Windows Phone 7). Sometime ago I saw some screenshots where I saw a little “Sign in” link in the top of the Zune Software, which I had never seen in my version of it.
I tried different things like reinstalling etc., but it didn’t work. Even though it were pretty annoying to me that I didn’t have that, I forgot about this little issue until today.

I talked with a guy over twitter, who asked me to try and change my Location to US instead of Denmark. I did, and bang! it now works and I can browse for Windows Phone 7 apps etc. Pretty cool 
So go to the Control Panel and find “Region and Language”. You should see a window like this:
After you changed it, open Zune again and it should work.
Before my Zune looked like this.
Now, after changing my Location, it looks like this. I can login and have access to the Marketplace. Many of the Zune services isn’t available in my country so I can’t buy anything, but still I can browse the Marketplace which is very useful for me these days.
