Computer to computer issues

Rhino 6 is the only program I use. I have it on my laptop, and my desktop. I saved about 10 drawings from my laptop onto a 32 GB USB card, both in .3dm and .dxf format. I tried to open these files on my desktop computer, and the curves are invisible. All of the default colors are being used, and they are all fairly simple drawings. I know the curves are there, because I clicked around and found some. I tried highlighting them by dragging a rectangle over the curves, but I am not getting anything.

I run the program on default settings, on both of my computers.

I feel like it is odd that I am having this issue?
