You can't do anything against an Error 7.
It's unknown how or why, but you hit an timeout.
Maybe due to latency.
1mbps? That's slow, unless you mean 1 MB/s ~ 8,3 mbps
I have 3,6mbps (around 260 KB/s) which is enough.
Minimal speed working with World is 7,5 KB/s ~57344 bps (around dial-up or EDGE/GPRS speed)
I am also in the german EA Forums, helping with technical problems.
