Ah, thanks. I only have three apps, Swype, Big Screen and Joiku Spot, it's the latter that's missing. I checked online to confirm that it's on my purchases list, but it does not come up on Nokia Store (I upgraded from OVI Store)?
You should have the free version anyway. Might you have bought the paid version directly from the Joiku site? If so they will have emailed you a copy of the transaction and an unlock key. If you still have a copy just re enter the unlock code.
