Premiere Pro CC locks up when trying to change file name
So I'm on the latest version of PPCC and I'm having trouble when I try to render a sequence.
When I go to the rendering options window and click on the filename to change the filename and the export location, Premiere Pro just hangs. I get an infinitely spinning circle of death (Windows 10's version of the beachball of death). I can't even close Premiere and restart - i have to totally reboot my machine.
I get this with any project / sequence. Sometimes I can get it to stop when I disconnect my external USB 3.0 drives, but that's a no go because that's where all my footage is. Does anyone know how to fix this?
I'm on a Windows 10 MSI laptop, i7, 16 GB RAM, GTX 880M with the latest drivers.
