I apologize for the trouble. I will need some more information to trouble-shoot. My guess is that there is some gpx file on your devices that BaseCamp doesn't like.
Can you try to backup and delete all *.gpx files on your devices Garmin\gpx folder (and subfolders if present). Does it still crash then?
If it doesn't, try adding back the gpx files till you find the culprit. I'd be interested in seeing the file that causes this, so we can make sure BaseCamp doesn't crash like this in the future.
Does BaseCamp's error dialog pop up and did you report the error to us? If so, I'd be interested in the file name and line number, so I can look up the crash in our reports.
Or does it just freeze? Or does it show a generic Windows error dialog?
There is a dialog pop upthat I have send the reports. (29-9-2012 16:20) The file name: minidump <?xml version="1.0" encoding="UTF-8" standalone="no" ?> - <ErrorReport xmlns="www.garmin.com/.../v1"> - <Error> - <Exception> - <SourceCodeLocation> <SourceFileName>SYSTEM.WINDOWS.FORMS.CONTROL.MARSHALEDINVOKE</SourceFileName> <SourceFileLine>2447</SourceFileLine> </SourceCodeLocation> - <Extra>
I have had pretty much the same problem with frequent crashing after update but fixed it by updating the software on device to the latest available…
