I am sorry to report that we have suffered with memory errors in our firewall since the beginning of 2011. Only now have we confirmed this, by replacing the firewall memory stick. Our memory errors appear to be gone - given the last 7 days of testing - and we have taken extreme measures to prevent future issues.
I hope your game experience is improved as a result
P.S. Our firewall now has twice the memory than when it was shipped from the factory!
