Stopped working – Handwriting Without Tears: Wet-Dry-Try for Capitals, Lowercase and Numbers—Classroom Edition Review

Initially worked for 3 letters. My son took a break & now I can't get app to work. Super frustrating. Caught in endless loop of opening app, requiring sign in to "wet, dry, try" website (not app - website where I bought the license to use app) and even though I am logged in, app won't recognize it. App won't load. Support FAQ says to contact Apple, not HWT. Frustrated & feels like a waste of $5. Ugh.
