You're the second person to complain today. I'm wondering if there's a bug in somewhere. The IDE is supposed to alter your trust file for you. You can set it manually. Look up FlashPlayer Trust files on the Adobe site for how to set it up for your particular OS.

Thank you sir! Should I file a bug?
just a quick check before submitting a bug report. try restarting the browser -- i've fixed some security issues this way.
I tried that. Also tried reinstalling beta2, since I thought I just installed over beta1.
