How to upgrade a Try and Buy product at RIM/BlackBerry App World
It appears that a lot of people experience problems while purchasing Try-and-Buy products from App World. In most cases you can download the trial and even purchase the full version but you are not able to download it. In fact in the last few days we received a lot of support requests that describe the same issue.
We identified the problem and it is in the App World, not in our application.
What I’m offering here is not general solution for the problem. This is based on my own experiments, it worked for me.
Now, the details. The problem that I had was that I purchased Interlecta Translator (Try’n'Buy) but first downloaded the trial version. Unfortunately, after the trial period ran out, when I tried to download and install the full version, the App World wouldn’t let me do it. Actually, it will show me that there is upgrade available but will not provide a button to download/install the upgrade.
So, this is what I did, in result of which I was able to download, install and use the latest paid and fully functional version of Interlecta Translator for BlackBerry.
(1) First, I removed the Interlecta Translator from App World. Don’t worry, you will be able to reinstall it again without paying for it twice.
(2) Second, I removed completely the App World application from my BlackBerry. You can do that by going to Options / Advanced Option / Applications, where you should find “BlackBerry App World” and choose from the menu “Delete”. It is important that after this is completed to reboot your device - you can do this by pressing together the Alt-Shift-Del keys.
(3) After that I installed the App World again. You can do that by going to http://appworld.blackberry.com directly from your BlackBerry and follow the instruction. Please note that this is quite large application so it is good idea to turn your Wi-Fi on and use it for that operation. After that is finished you should reboot your device again.
(4) The next step is to start the App World and reconcile your account. This is very important. This will ensure that you are not loosing your existing applications, those that you’ve already paid for. You could do this by going to the My World, the icon at the bottom-right corner, and while there choose from the menu “Log In“. You will be prompted to enter your PayPal information. Please, be sure that you use the same PayPal account that you used when purchasing from App World. Upon successful signing in you will see a message that your conformation was successfully reconciled.
(5) Now you have to find the Interlecta Translator Try’n'Buy either by searching for “interlecta” or from the list on the applications under My World. You will see that there’s only one version and that’s the latest one. It will not ask you to pay again for it, because you’ve signed in. Just install it. After successful installation you may be asked to reboot your device.
(6) After that you’re ready to use the software.
