Windows 8 Windows 8 keeps signing me into a temporary account.

I've had my Windows 8 computer for several months... it's been working really well, absolutely no problems.

But today... when I turned on my computer... I signed into my account like always (the only admin account on the computer)... and it keeps signing me into a temporary profile instead.

A balloon pops up in the corner, telling me it's a temporary account and to try again later or something.

I restarted the computer about five times... but still... it takes me to a temporary account, rather than my real account.

Please help.
