Thanks for sending your installation through.
I notice you have "Auto-detect an Internet connection" turned on. When I wrote that bit of code, it turned out to be a remarkably difficult thing to determine accurately.
A giveaway that this is probably what's causing the problem is seeing the following message in the Activity Log:
Not connected to the Internet. Channel updates have been suspended.
This gets issued every 5 minutes if Awasu is not connected to the net.Or thinks it's not connected to the net
Turn this option off and your channels should start updating properly.
BTW, if anyone knows how to reliably check for a connection, please let me know! I'm currently using RasGetConnectStatus().
