Stuck on checkout screen

HI there,

I am trying to order the CC cloud, year pre-paid and it seems to be stuck at on the confirmation page with the small squares are spinning on the right.

I left it on over night and still it's at the same place.

I am using Chrome to make the purchase, on a new Dell i7 Precision notebook.

Should I close it and retry? I am just afraid of  my credit card being charged twice...

Any suggestions?

Thanks.
