Very interesting that preloader/priilaoder would have any effect on your channels.
I would ensure you have the proper system menu hacks.ini,
Test is hacks disabled has any effect on the issues. Perhaps you have a bad hack.
You should try priiloader 0.3b, download a fresh copy from the priiloader site.
If you really are having this issue without any known fix, you should make an issue report with as many details as possible on priiloaders google source page.
I suspect it is somehow you and not priiloader, as many many people have installed this.
Any chance your ran dop-ios-mod v11.3 or 11.4? those have a know bug, which kills channels.
