I do hope someone can help me

All my content in Daz Studio 3 Advanced just disappeared, so I did a uninstall/reinstall of Daz Studio several times. Everything was weird when I opened it. Can't install other content either. I even done a Systems Restore without any luck

I tried installing it on a friends pc and it installed perfectly.

Above is what it looks like it even installed the runtime.

Thank you for any help
