Converting large ACAD files to VISIO wire shapes

[Grey Wolfen]

Anyone out there having Visio 2013 stop working in the middle of converting a 1.5MB ACAD drawing into a Visio wire shape? I import the CAD drawing file (although I have to hunt for the drawing) I right click on the imported CAD data, tell Visio to convert it to a Wire shape, it starts to do the conversion, and then when the process bar is about half way through Visio quits and tells Windows 8 that it stopped responding. Which Windows 8 restarts the program not finding a solution to the problem. Any help that anyone can give on this would be greatly appreciated.
