I have had multiple drawings from my instructors that I have copied and pasted from a school computer to a flash drive. When I try to reopen the drawings at home on my laptop I get a notice that the dwg cannot be loaded due to it was created on a newer version of ACAD. And then prompts me to load Autocad TrueView. Which has not yet downloaded properly. The open and save options are set to ACAD2013LT at school as well as on my laptop.
