About snoopper error msg - it's not actually error, but some kind of a warning. Like: "you hosted too many games recently" (still able to host, but that msg is just annoying). I guess snooper creators would do something about that in next upgrades. We'll be patient until then.
About replays (thx Walrus, btw) - maybe it's not wormnat2 thing and problem is just my modem. But highly doubt that, cause it happened 2 times in 15 mins. Before update I almost never got disconnected.
About worms version and built-in wormkit support - don't know man..it's like you talking to the wall atm

Gonna try fix this, if I found solution, others experiencing similar problem (if there are any) will be informed.
EDIT: using 3.7.2.1. if that was your question.
