Final Checklist

• I've checked to make sure that this issue has not already been filed
• I'm reporting only one issue in this ticket for clarity and focus

Does MML function normally after getting these errors? The first time MML is launched, it is expected that your preferences and the unit cache will fail to load, but then they should be built up and normal operation should resume.

[rjhancock]

The first errors can be ignored as the app is just trying to load a file that doesn't exist and re-builds as it needs. The second set of logs is the actual error that might need to be addressed.
