thanks for testing.

@samb:
there is multiplayer8 demo converted from AUM77 to GSTNet on my website as a start.

bug confirmed: you have to call _SetVerifyKey(_str("MUST_NOT_BE_EMPTY")); fixed in 0.7.2
@Quadraxas: i have no vista machine atm, could you try GSTNet-LiteC with

GSTNet_ChannelStart(player_name,_str("TEST"),0);

instead of:

GSTNet_ChannelStart(player_name,_str("TEST"),1);

this means no usage of channel service = http requests.
