Files have no data

I have been downloading some project files from the CutRocket - CNC Project site. Problem is when I unzip it and bring up the file in Carbide Create V8 software it shows up blank. What am I missing here?

I also wanted to say that this site and this community have been great helping me get started on my journey. I hope to learn and get started helping others one day.

Example of a file:
5bff48d9d2d71_5c072e100fa32.c2d (429.3 KB)

As noted on the announcement page:

  • Create V6 files do not load into V8

You will need to download v7: Downloads and open any v6 files in v7, resave them as v7, then open in v8.

Thank you, I thought it would just be upward compatible.
