Attached trace files

I downloaded the log and trace files then removed them from your post. I would not recommend ever posting these files publicly as they may contain sensitive information.

I'd like to try to reproduce what you're reporting. To do that, I'll need your workspace and template files.

You can send me these files by going to the Control Center-> Help-> Email Support

• Expand 'Other files' and enable 'Workspace files and UI settings' and 'Template files'
• Please reference the following ticket number in the body of the email: 1860052 ATTN Patrick G

Microsoft ended mainstream support for Windows 7 on January 13, 2015. Maybe that's a problem.
