They have an IRC channel

http://chat.efnet.org:9090/?nick=&channels=%23SmoothStreams&Login=Login

They've always been helpful on there whenever I needed something.

Please do not post SSTV support questions in general IPTV thread. Not appropriate place to post this, also, you must have patience, nobody works 24/7. You have been added to r/SmoothSreamsTV. We just re-opened registration, so maybe that is why it didn't work automatically. Normally, as soon as you pay you receive access. You have submitted a support ticket, as well as PM'd our team here. Please remove this post. You will be helped, no need to panic and blanket all of reddit :)

This happens now and again. Reset your password I think does the trick! Also, I paid my subscription yesterday (been a member for four years) and the streams started working within 2 seconds.
