so i run draftsite on 2 computers, one in the house and one in the garage with my plasma cutter. have just upgraded to 2017 on both computers and now when i save a file to a thumb drive on one I can open it on the other but i can not make any changes to the drawing. i can add to it but can not do any think with what is already there. Is this because i am using the free version or are my settings wrong somewhere? I can not edit a file sent to me by others as well. it seems i can not edit any saved file!
