PhrasePump error

I’ve been using Language Reactor for about 2–3 weeks, and I’ve never had a Pro subscription.

For approximately one week, I’ve been unable to mark words as “Learning” or “Known” in PhrasePump. Whenever I try, I get the following error:

“Pro features are no longer available.”

PhrasePump was working normally before this issue started.

I’m using Google Chrome, and my internet connection is working normally. I would like to know whether these limitations are intentional changes to the free plan or if there’s a technical issue with my account.

Could you please clarify this and help me resolve the PhrasePump issue?

Thank you for your help!
