Recover application / Transfer license
Android Market applications when bought are bound to your primary Gmail address (the one you have used to set up your phone). If you have used the same Gmail address, it should appears as purchased in the Android Market.
In the case of that still does not work, the only solution is to rebuy the application, then to send us the previous order number and the new one, We will operate a refund on the old order. That is the only way to transfer the license.
