Loaded MC25 to eval (have license to 19). Somebody is calling the windows function SleepEx on a UI thread, which is a bad idea. Send below to your devs. Contact me via my registered email address if you want a dump/cab for this crash. It dies while sitting there doing nothing, it dies while doing file format conversions, it dies while trying to perform DLNA operations (which by the way don't work, trying to control a PSAudio Bridge II).
JRiver 25.0.114 (64bit).
