The reason players disappear is not always they quit, biggest
problem is that they are using a 32 Bit Operating System, which can only use 4 Gig
of mem, regardless of how much you install. One now needs to upgrade to a 64 Bit
Operating System.
I run a 64 Bit and I have 25 Gig of Mem and I never have a problem
with downloading and I always download the fastest, like instant, while others rings
keep on going.
