I am trying to launch the app and keep getting this error message.

Error message copied to clipboard:
Unable to remove broken app settings file
Please exit the app and manually delete folder C:\Users\19195\AppData\Local\Britton_IT_LtdStack trace: at CrewChiefV4.MainWindow..ctor() in C:\projects\crewchief_c_sharp\CrewChiefV4\CrewChie fV4\UserInterface\MainWindow.cs:line 1173
at CrewChiefV4.Program.Main() in C:\projects\crewchief_c_sharp\CrewChiefV4\CrewChie fV4\Program.cs:line 133

I have deleted the app and downloaded again, tried the repair feature in Setup Wizard etc. but nothing seems to work.
