Please read carefully what I wrote about it - you can use it BUT only with one opened instance at a time.
No, you never mentioned that you were using one PC only in that post and you never wrote about a script that will access the database too
I just explained to you when the db server could help you and what it does regarding to this information.
And when I asked you about your setup in a PM, after you posted and deleted a thread with, for me, confusing informations and obviously after you bought the advanced server version, you then told me about your special setup on a virtual computer with virtual cables‘ audio routing and playing from two playlists sometimes. And using a script.
So how should people know that you are going a route with your mAirList that isn‘t standard by far?
Btw: Of course you can’t change the ID of connected database by using the internet client connection - every user would then be able to change the ID of a remotely connected DB and make it unavailable for all other connected clients.
