This is not an error ... you had 2 states originally in the return so the .taxfile has both state's in it so to open that tax file you must install both states again. In the future, if he is not required to file a NH return then don't complete a NH return.
If you had paid for the second state program you should be able to download it now ...but if not contact TT support for assistance.
