V1 files created on a PC store OS specific path delimiters in the .ormdesigner XML file.
This causes an issue on OSX which crashes ORM Designer 2, and seems like this will be an issue with any cross OS development that might be done on a team.
Changing that line ( an any other line pointing to an external XML file ) to the following fixes the issue on OSX:
All that changed was update the \ backslash, to a / forward slash.
This will update the .ormdesigner file to work fine on OSX, but now it is likely broken for PC users... I know our projects are under a git repository and a developer can use any OS to edit/update the project.
So having a method in place to handle how each OS uses a path delimiter would work well to insure that ORM designer projects can be cross platform as well, not just the App ;)
