RankerX Closed?

Hi, I bought lifetime license about 3 months ago. Today, my server got restarted and I cannot access RankerX. I would like to reinstall it but when I open the download page. It said " 404 not found". Anyone facing this problem? Please kindly share your thought

It works just fine on my end,
