AIMP 4.x is a large departure from AIMP 3.x, so I'm posting a development test to ensure it both works right and handles upgrades from 3.x properly. Multiple settings files get renamed and some are no longer used as the UI has changed drastically.
Please try both clean installs and upgrades and report your results. Please be sure to backup your existing install before using.
Thanks
