I am migrating some schematics from PADS 2005 to PADS 9.3.1. Our schematics are stored in Tortoise SVN repository for version control. When I open the schematics, (projects) in 2005 they are fine. I can run the Schematic Checker tool and everything is good. When I try to open them in 9.3.1 I get a message that says my WIR files may be out of date. Any ideas as to what may cause that error?
