Hi @John. The new AndroidPIT app v2.x cannot install apps for you. It simply replaces the old ''content'' app with a new one. The App Center app - downloaded from http://www.androidpit.com/install is and always has been the one to use for installing and updating apps bought from AndroidPIT. So you need to have it installed for your purchases and updates to work. We know it's a bit confusing and we apologize for that, but we couldn't update everything at the same time. It sounds like you do have that app installed already, but I have to double check!
However, it is up to app developers to upload new versions of their apps to our servers, so if you aren't getting updates through our App Center, or you can't reinstall, then you need to contact the developers to ask them what's up. This basically means we either don't have the latest version on our server or the whole thing has been removed by the developer. Because the app is theirs we can't take updated versions and distribute them to our community unless they give us the permission to do so (by uploading the new versions). I know we've had questions about Beautiful Widgets before.
Juts let me know if you have the App Center installed and logged in (go to My Apps in the bottom right corner to view and reinstall paid apps) and if Beautfiul Widgets is still not able to be installed, let me know and we can either refund you so you can reinstall from the Play Store, or you can get in touch with the developers.
