We had a configuration issue on one of our automated build servers that released a development version of Roast Time under 2.0.7 for Windows. We will update the 2.0.7 version to the stable 2.0.7 and re-release. Please re-download 2.0.7 manually if you are affected by this issue!
Note: Due to database schema changes, you MUST run the stable 2.0.7 and likely are unable to downgrade. Sorry for any inconvenience.
