2 Apple TVs with IPTVX running on both, only one is working.

[RandyG]

Hi there, hoping someone can help with this..

I have 2 Apple TVs, both running IPTVX (the best App I have found). One is in my front room and one is in my office.
One works as intended but the other will not load any content, can someone tell me why? I never use both at the same time.

TIA
