I had MLCad on a previous laptop and it worked fine. Since I got a new laptop and installed MLCad on it, everytime I try to enter into a list of parts, I get an error stating that "File x-yedge.dat" not found! Continue loading?". The x is usually the nuber 3 but the y changes depending on whether I go into the pllates or bricks or train list, etc... It seems as though I am missing something that makes up various parts. I've tried twice to unistall and install again but I get the same error. Can you please help me figure out what's wrong? Thank you.
