Thank you for your post and problem details.
The first item I noticed is the Fault Module Name: 360Works_Email.fmx64
360Works_mail.fmx64 is a plug-in. Try disabling the plug-in and removing it from FileMaker Pro. Launch FileMaker Pro again and see if you still get the error. If so, post the problem details again.
I removed the 360plugin and was able to open FM. There musts be an issue with the plugin.
Thank you for testing.
360Works is very reputable and widely used throughout the FileMaker community. I suggest contacting 360Works to make sure you have the latest update, or see if they have previously run across this issue.
