Robh, what version of Reaper are you running - don't think anyone has mentioned?
Are you disabling your antivirus or white listing the BIAB executable?

It may just be something simple in your configurations.

PGM needs to provide a diagnostic file which records errors which we can send to them to troubleshoot!


BIAB – 2025, Reaper (current), i7-12700F Processor, 32GB DDR4-3200MHz RAM, Motu Audio Express 6x6 - My SoundCloud (Tip: No need to create a SC account to hear music - just hit ESC ).
