Sorry, I can't exactly figure out what is the comlete problem. I know you had just bought Rival Ball (probably Series 1 or 2), and you are saying you can't play past board 4, then you did, and then board five tells you to download the game again... either there is some new unknown bug around here, or you just played the freeware RB boards... (I think the second one)... If you bought and downloaded the Series 1/2, go and install it, it should install itself in the LDA Games folder. When picking out a board, you should see 8 boxes above the list of boards you can play. The ones in color are the ones RB has detected, and you can play them. Click on the one(s) in color, and you should see the new boards... that you bought... drop by if you have any more questions... :)
