Beware, can't restore purchases – Sudoku of the Day Review

I've used Astraware apps starting with Palm, through WinCE, and now iPhone. Purchased this when it first came out, and have used it across several devices as I've upgraded. Now the Restore Purchases option no longer works, just spins forever. Contacted Astraware and got no response. Add that to the fact that it isn't optimized for the iP5, and it's a sure sign that it's time to move on. You've lost a loyal customer.
