I just bought the Pro version yesterday. Had this happen to me today with a Dasaita Android head unit for my car. VERY annoying. This scheme is unnecessary and a big hassle for the purchaser. I will not have wifi 99% of the time I use this app. I made a forum post before I did a search to see if others had this problem because I was so annoyed. Really bad licensing scheme. If it's not fixed, I guess I will go back to Pulsar, which was very good, but lacks the visualizers that impressed me so much. But nothing is worth this hassle.
