CCS/TM4C1231H6PM: Errors in Run/Debug Settings

Part Number: TM4C1231H6PM
Other Parts Discussed in Thread: CCSTUDIO

Tool/software: Code Composer Studio

I'm getting errors in Run/Debug Settings and breakpoints have stopped working.  This has been working fine in the past.  If I select "Edit..." for my launch configuration, or if I select "New...", I get the errors:

Exception occurred creating launch configuration tabs

Reason:

No tab group defined for launch configuration type com.ti.ccstudio.debug.launchType.device.debugging

--- When I click "OK" I get the error:

No tabs defined for launch configuration type Code Composer Studio - Device Debugging.

--- CCS version 8.3.1.00004

Thanks, Doug
