My Eagle software has become totally unusable and I can't figure out how to fix it. Sometimes it stops working as soon as I open a file. Other times, it waits until I've made a change or two and then it blows up with just a "eagle.exe has stopped working" error. I've uninstalled, deleted my eaglerc.usr file, and reinstalled the latest (6.4.0) version and I still get the same results. Any ideas? I'm totally dead in the water.
