Great app but serious problems updating.

Ive been using this app for a few years now. And every so often it asks me to pay for packages Ive already paid for. I dont think much of it because I just click restore previous purchases and everything is as it should be.
However, this no longer works after the most recent update.
Fix this and Ill change my rating to five stars.
