Bought an unlock, wiped out by upgrade

I downloaded the read-only version and found it met my (minimal) needs well enough, so I bought an unlock via the app store. Two updates later, it’s back to being locked to read-only even though the store still shows the unlock I purchased. It offers to let me pay another $20 for another unlock. Needless to say I feel ripped off.
