Open Newer Version crashes SU 2017 every time

I just downloaded Open newer sketchup extension to my su 2017 but it crashes sketchup everytime I try to open a file.
I have tried restarting the program but same thing happens

Turns out to be my fault, it didn’t occur to me that it was Windows only when I suggested it.

How many tutorial files do you have to work on?

Just noticed something, if you’re doing the tutorial I think you are, there are 2016 compatible files included in the download. Look to see if you have those, they should open in 2017 ok.
