Weatherflow Add-on Missing?

I am new to Home Assistant and I had added the Weatherflow integration from the store as soon as I got HA installed. The add-on needed no configuration and just worked. My machine promptly crashed and totally burned and now that I am back I can’t find this add-on. I see a Weatherflow MQTT version but it looks like it needs a manual installation and this is beyond my current skill set. I tried to add it my clicking on the add but this takes me to a login and when I try and add it there is says it is already in the store. A infinite loop.
