I got it working. I think the sample rate and number of channels in the project was different from the settings in Preferences and/or the mixer sampling rate and it was throwing a “Input port not open” or something error and crashing.
I unchecked the box that says “Show me this error again later” or whatever on that ASIO error dialog because that thing was popping up like crazy.
Anyway, it seems to be working now. Thanks for the help!
