After you file

@N ick Name

IF your Illinois file was supposed to be  your Free one

1) Exit the file and back to the starting home screen
2)  Run the software Update again from the menu again
3)  Start a  NEW tax return as a dummy-file.  Put in enough Personal info to indicate your resident state (IL)....then go to the state section and see if you can download IL as the free state.  
4) IF #3 works....Then Save-AS something like "Dummy-ILL"  so you don't overwrite your real file. then go back to your real tax file.
