Rhino4 to Rhino6

Some years ago I did some work in Rhino4 that has sat on the shelf. There was a lot of work getting the model into digital form. This project is starting to get active again and when I opened the old files in Rhino6 I got a wire frame image that I couldn’t do anything with. In perspective it rotated and panned just fine. I could select curves but could not do anything with them. Line intersections would not respond to the cursor. I still have my old Rhino4 disks, but I don’t know how they would be useful. Any suggestion how to capture the old data and import it into Rhino6 would be greatly appreciated.

OOPS!!! Disregard this post - OSNAP was turned off for some reason… Problem solved…
