I just updated to the new store today. Tried buying the season pass for ACIII, but I couldn't add funds. So, I went and got a digital code from Amazon. Got that, code worked fine. Then when prompted to put my password in during checkout, it says my password isn't valid. Strange considering I had to put that same password in just to get online. This problem started once I updated to the new store. I actually bought something last week before I was forced to update, and I was able purchase everything. I guess I'm not the only one having problems with the new store, but I thought I'd throw in my experience anyways. :/ Hope a solution is around the corner.
