It's a long shot, but I wonder if anyone else has had a similar problem and fixed it...and apologies as this is probably not strictly an mAirlist issue.
I'm trying to run Zara Radio and mAirlist on the same XP machine. Unfortunately if Zara is running, mAirlist cannot start. If mAirlist is running, Zara skips audio.
When I try to start mAirlist it reports something about kernel32.dll as well as a ton of other gobbledegook.
I'm pretty sure this is a problem with Zara, not mAirlist, as Audacity will not work alongside Zara either.
I'm on v 2 mAirlist - 2.1.44 if I remember correctly. Mairlist plays through a Maudio delta 44 sound card, and Zara through the on-board standard sound card.
