[Update on website says it is corrupted for 4.7.1]

The link on main site says it is corrupted and I am unable to download it, is that from my side or is it from the server side.?

[Ultimaker cura version 4.6.1]

Hello I am having issues with my slicer program , it will load stl and you can move it around etc, change settings and whatnot, but it does not slice or when it does it takes forever , and the last one it sliced it just started moving the printer all around without heating etc, just started moving it around.  Any ideas.  I love the software and can not think of any changes i have made to cause this.
