I just got the Go Pro 3 and found that it doesn't recognise the Sandisk Ultra microSDXC 64 gb card. Not sure what to do :( Any ideas? I got this as it is a class 10 card and recommended for HD video.

I use a Kingston 64G micro SDXC card in my Hero 3 Black Edition and it works fine.

There are known problems with that sandisk card. Best to try another brand.

Ha! What does one do when he's already bought 6 of those 64GB Sandisk cards and opened them up?

Return them to Sandisk for refund (exchange?)

Apparantly Sandisk had a manufacturing problem. Hopefully it is resolved by now.

You need to format as exFAT. You know that, right?
