Lost all the unlocked puzzles

Just installed the update and now by adding all the lowercase letters as well, the puzzles i unlocked when i bought it originally are now locked and want me to buy them again. Not happy!!! Want to find out how i can get them back. Dont feel like i should have to buy them again.
Son really likes this puzzle game. Learned alphabet and order quickly.
