G'Day Dave,
If you have not already, try ...
Close the Spot Log, and any other active tools before the import.
Check the ADIF from Writelog for "invalid values" ... alpha chars in number fields etc.
Run clean, and limit other functional activity while you do the import.
Search the Forum for "adif import" for other potential ideas.
