Buy the MacOS version AGAIN?

So, I started up my copy of iReal Pro (I don't know when I bough it - it was long ago) and found that it wants me to purchase it again.
I have already paid for it and imported a ton of charts and what not, but not it wants me to buy it again... I am confused. Is anybody else having this issue?
