Hiya Sue, Welcome to WinmxWorld,
yes its possibly your provider,
a while ago i was told that Talk Talk had merged with Tiscali, who also merged with AOL,
now these three was known as the worst in a top 10 list of providers that throttle users,
now they definitely hold the no#1 spot, they use a packet sniffer to analyse packets sent to and from, winmx uses such packets,
they can block the ones they want, so with a large motd, it wont all load and you wont see a user list, this is common throttling,
the only 2 options are,
1, depending how long your contract, wether you can change provider
2, use a proxy, but so many rooms use the proxy blocker now, due to spammers.
