I did install  on a Slate7 without a BIOS update but I'm not sure which version I have. I just got my Slate7 2 weeks ago.

Unfortunately I have some other problems wit Win8 Beta. I can't install anything from the Store, can't sign-in to Music (Zune) or XBox Live.  I get the error "Sorry, sign-in isn't supported in your region at this time." Any other people here from Canada experiencing the same problem? My live account works fine with Zune on W7 and on my XBox. My location of my Windows Live Account is set to Canada as well as the location on my Slate7.

Please don't tell me Canada is left out from the most important online services.
