Market error.

Me along with some friends have been having trouble buying items off market. The majority of the time we get an error please check your connection. When my connection is fine, because I did just load the market and scrolled through a couple of pages. Tried reinstalling, rebooting. Been having this problem for a week.

I believes the message pop up because you can only buy certain amount of item from market. Buying resources is fine but not equipment. I think the maximum amount of equipment you can buy is 3 per hour or 24 hours. I'm not sure.
