Glad the OP's problem is solved. Rather than two threads with the same subject, I'll mention my issue here.
My new Surface Pro (not RT) sometimes doesn't sleep (or wake) correctly and ends up going through a full boot when I turn it back on - nothing previously running is still running; when I launch IE it says my session ended abnormally; etc. To be truthful, it wasn't on Windows 8 long enough for me to notice if it's an issue specific to Windows 8.1, as I upgraded to 8.1 RTM within an hour of buying the thing.
Amazingly, it did not do it today. The only thing I remember doing differently was selecting "Sleep" from the start button last night instead of just letting it fall asleep on its own.
