Problem with Bubble Breaker (Pure)

[anken32]

Hi, I have downloaded & paid for the Bubble Breaker Pure Version.
After downloading this app, it doesn't show on any start up screen. It shows up in my app. page as installed along with the other apps I have downloaded. The only option available is to uninstall. I have even done that and reinstalled but with the same results.
I have tried to contact the developer but have not been able to get any answer. It's frustrating!
Does anybody have any problem with this app.?

You only have the key to the full version installed. You need to install the classic free version and having the key installed, which you purchased, will upgrade the free version to the full one. This is fairly standard with many apps.

Thank you for your tip. I will keep that in mind for future reference.  Still have a lot to learn about the Android System but it's great.
