Quickmap can give this error:
Quickmap: Unexpected Error Encountered
COMException (Error HRESULT E_FAIL has been returned from a call to a COM component.) in method UpdateToolbar of class FrmQMap
A further look into the support log may show this error:
InvalidComObjectException (COM object that has been separated from its underlying RCW cannot be used.) in method Map_QOnPaint of class FrmQMap
These errors come about when there are error in (or missing) data.
