I don’t think they are still offering the 45%.
Wager Junction has taken them over a few months ago and I believe they now only offer 30% to new affiliates. (I know the Windows Casino site says 45%… they have not updated it yet.)
I like Windows Casino. It is one of my top earning programs and in years and years (can’t remember for sure how many) I have only had one player complaint and it was not valid, (the player wanted to deposit and then withdraw all funds within an hour and was a bit peeved they found it was going to take more than an hour just to clear the deposit).
