Hi all,
Thanks for your patience and understanding with this one. Also, thank you to those that responded to my private messages - you were very helpful.
We recently updated the framework (Electron) that our desktop application uses and we think that may have led to a problem on some Windows devices which can result in the freezes, black screens, and crashes described above. 
For the time being, we’ve “rolled back” our Windows application to the previous version while we find a more permanent solution. Anyone on Windows should be prompted to update the next time you open TrainerRoad; if you continue to encounter these issues after completing the update, please let us know!
If you are encountering an issue on a non-Windows device, you should reach out to support@trainerroad.com and they will do their best to help you out.
