Thanks to VolvoGirl and Mike 9241 for the suggestions. Some more information:
1) I did not install an additional state, only the state that came with the original software
2) If I go to my Intuit account, it confirms that I have 2024 Federal AND STATE
3) If I download the file from the link on that page, the file that I get appears to be the same as what I get by going to the TT website directly. I used it anyway with the same result.
4) I have always removed TT using the Windows "Add or Remove Programs" in "Settings". Presumably this should have taken care of Registry Keys etc.
HOWEVER
When I reinstall TT 2024 I am not asked for my license code so that is evidently left somewhere on my machine.
IN THE END
With all the remove programs, restarting windows etc. the result is still Error 190 and a prompt to pay $45.
Has anyone had any real success with support after staying on hold?
