recording from live streaming cam. help recording rtmp .flv with Replay Media Catcher

Hi im new to the forum, and need help
Ive just downloaded the Demo version of Replay Media Catcher, ive been trying to record from a live streaming cam, but i think i must be doing something wrong, it says that its recording, but when i click "stop recording" it still carrys on, even when i have clicked off the flash cam page, also ive tired to look at what i have recorded useing the "transfer" tab and then clicking the "play media" tab, but for some reason they are greyed out, and i cant click on them, am i doing something wrong?
Here is the url that i have been trying to record
rtmp://38.98.53.172/ep

I will be greatfull for any help
thanks
