Excellent.
Will give that a go. Havent had chance as yet to download the latest version so will try it all later.
It may also be worth doing a Search on your PC for BASS.DLL.
When I initially installed mAirList, I found one or two other BASS.DLL files which had been installed by other apps., including one in my system32 directory (!).

Just make sure that there is a BASS.DLL in your mAirList folder. mAirList will not look into any other places if it finds one in its own directory.
Looking good - let us know as this develops
