Does Not Work For ME

So... I am trying to run this blindly because the tutorial video links to a place that does not exist anymore.  Every tome I open the pkg I get an error message
Then I actually do figure out how to get the files in the first tab,  I don't know what to do, so I 'save state'.  it looks to be a zip saved using the invoice numbers and RDY I input, but when I try to Load the State to create metadata, I get an error message and it never unzips.  

It would be a cool program if I could get it to work or had any idea what I was doing...

Unforchenly the creator of the video @MrMechano hasn't been around for a while.
When I got some free time I'll see about creating a new video.

The first error can be safely ignored as that is an original Daz file CDDS is just letting
you know that the file doesn't conform to CDDS's DIM standers.

As for "save state/load state" only works for a DIM that you have started making
metadata for.
