I have downloaded certain paid-for apps on my BlackBerry with my BlackBerry I.D. I have recently got a PlayBook tablet and even with my BlackBerry I.D signed in it does not say on the 'My World' section of the app world that I have downloaded them. For example, the Chess app cost me 99p, however the app world on my tablet asks me to pay for the app again to download it. Any help would be appreciated ! Thanks.
