Error in VA e-file attempts say "Request failed: bad request (400)

Please help!  I tried to e-file my federal and VA state return together but kept getting the error message "Request failed: bad request (400)".  So I e-filed just my federal return and it went through.  Getting the same error message when I now try to e-file my VA state return by itself.  In review process prior to e-filing, it says no errors and ready to e-file.  I'm using the TurboTax CD for Home & Business for Windows & Mac.  What gives?  I've paid to e-file my VA return so I'd rather not now have to file by mail.  Help!
