...and needs to close. Why is this? What can I do? I dunno what's wrong?

Not enough details here to even start guessing. Think like a detective and give
me everything I need to make it happen again, including precise details like
version numbers of BearFlix and operating system and exactly when it happened
and what you were doing at the time.

I'm running XP and version 1.1.8.1

It happens at random times, it could be running awhile and I'll be doing nothing to it, and it just shuts down, or sometimes right when I connect. It just depends, no certain thing sets it off as far as I can tell.

Get a copy of [StartupList], run it and post the resulting report.
I suspect there may be a software conflict we can resolve here.

Okay, use the Options menu to override skipped items like it said so you can get
the report. Those domains were probably added to Internet Explorer's restricted
sites zone by some protective software to defend against bad websites.
