I'm using Windows 7 on my PC. Not sure about going to Windows 10 since I have it on my laptop and hate EVERYTHING about it, although at least it's not as bad as Windows 8.

From what ReptaarRawr said, it seems the problem appears to be very common with people who play from South America. I might look into WTFast to see if that gets rid of the problem. If it proves to be a temporary fix, I might just put up with it until they manage to fix whatever the hell seems to be going on. ~__~ What annoys me though is that:

1. In the morning, the freezes don't happen. Then again, in the morning there's barely anyone playing, meaning queues take FOREVERRR!
2. All my other games that host their servers in the US aren't giving me any trouble (tried with BnS, GW2, and D3).
