Looking for some advice on the In Game Store. I've been playing for over a year and this weekend all of functionality of the store stopped working. No links work and I can't type in the search block. I have tried this on two separate systems (one running Windows Vista and the other running Wondows 7) On Vista I can see the store and can't use it. On Windows 7 I only get a black screen. I have plenty of points. Anyone know if this is a system, computer, or account issue?
