its partly my fault i guess cause i never freeze to tracks on anything, but when u get that blue circle spinning.....do you wait it out? or nothing happens i guess?

is there a way to bring it back from that circle thing to save the session or its gone once u get that circle spinning

 

I completely stopped using shitty iZotope, Waves and all iLok-protected plugins, and no problems since then

 

Wait it out. Most of the time, Reaper is working and will come back -- could take minutes. You can analyse that it is working, as opposed to crashed, by using any process info tools, or even just task manager.
