Zoom auto deleted from my computer twice

Is the second or third time, zoom disappears from my computer and I have to reinstall it. May anybody tell me if this is ok?

And  although I am a paid client, it does not recognize me when I install again the desk application

And there is no one to contact to.... and eith the new design I've lost the board where I had my different pre set meetings....

I used to love zoom... but now wondering.... @xx87_2
