Hi Joe,
Skipping while broadcast is usually caused by other software running on the computer that is preventing PlayIt Live from sending the audio fast enough, or reading the audio data from disk. It can also be caused by your streaming provider, usually ones that are free or very cheap.
Please can you show a screenshot of the specification under Help > Spec Check and also the programs running under Task Manager: right click the task bar and select Task Manager, expand More Details and sort by CPU.
