this program sucks big time, it is highly unstable. i paid for it and have been trying to use it to run a radio station for the past 3 months. what you will encounter after you leave it running for awhile, is what they call "audio skipping" basically the encoder screws up, so you have to restart the software. this week i've had to restart the software 5 times to get the station back so people can connect, which has done serious damage to my station's reputation. i just can't believe they would put such an unstable build on the market, but i guess people's greed comes first in today's market/world. it's really easy to use, but they need to work out a bunch of problems before it can be relied on. i'm using version 1.8.9
