If iCamSource is crashing, there will be crash logs.
I'd like you to look to see if there are any crash logs.
The crash log would be in:
/Users/<Your Username>/Library/Logs/CrashReporter/iCamSource_<date_time>.crash.log
or in:
/Library/Logs/CrashReporter/iCamSource_<date_time>.crash.log
If you find any iCamSource crash logs, please email them to support@skjm.com and refer to this forum thread in your email.
