Broke my entire system

I bought my first Plugin the Manley VOXBOX Channel Strip after owning the Arrow for about a year and the UAD software needed to be updated but I have a Mac with Catalina OS and it looks like there are bunch of us with our systems down. It not only doesn’t list the Voxbox but it has now disabled all of my plugins. I can't record anything. I have called for about a week and the customer service is playing a recording that they are closed. I have emailed a few times only to get an auto message return to send some files. I find it hard to believe UA can not be installed properly. I have spent over $600 dollars with UA and NO CUSTOMER SERVICE. Unbelievable. Truly dissatisfied .
