Hi everyone,

I tried the pro version for one month, and saved my works in Sketchup7 format, but now it's impossible to open it in Sketchup7 free (version 7.1.6859). It is really frustrating !

You have version 7.1.6859.
You need version 17.2.2554.

Do you have any piece of advice ?

thanks in advance
