What has happened to my premium account?????

I purchased a lifetime licence, copy of transaction here: https://drive.google.com/file/d/14oLyLsQN_S6AGomCsp3zhac-vIIIVd6d/view?usp=sharing

Everything has been fine up until now, when suddenly I appear to have lost all my purchased features, my website now no longer shows the hover images or the “more details” links, and one of my pages was completely messed up. And you are no longer treating me as having a licence. What’s going on?????????
