[Blind-sysadmins] importing database tables nightmares

Hi. Trying to import tables from a access 2010 database. And got sql server 2014 developer 64 bit for windows 7 64 bit pro. Now. I have the access add on pack. But it says when I try to login does not like the user name, but able to login and my user name is : MARVIN-PC\SQLEXPRESS And when I try to import a text file odbc driver, says it is not configured. Do I need to uinstall and reinstall. This is driving me nuts. Marvin. Ps: and I have a sql database with tables already.
