In game Store stuck on loading content

DomoSapien: So, loading issues for in-game cached pages can be caused by a number of reasons. If it's persistent, chances are it's not serverside because not everyone is being affected. 

With this in mind: my first recommendation is to perform a client integrity check through WGC. You can do this by opening "game settings" while you have WOT selected in WGC.

I would also recommend power cycling your modem, router, and PC just to be safe. If that doesn't help, our support teamcan recommend some additional troubleshooting steps and take you through some network diagnostics.
