Bad update with new subscription

I paid full price, 7.99 and have used this for 8 years. Now suddenly I have to pay every year I use it without warning. Updates came slow, not helpful, and now Im being charged yearly. Ive now switched to a different calendar app and will not use this. Ill be looking for the class action law suit regarding this.
