Used TT Deluxe 2004 pretty successfully, except for a few of the items on the "known issues" list (and an interesting workaround for registering the software...see prior post). Downloads for state forms and updates worked fine. When I finally tried electronic submission, however, a screen came up indicating that communications were being established, followed by what appeared to be a question box with gibberish for the question (button text appeared OK though). I clicked "cancel," then restarted the program and tried again. Same story, so I sent the tax forms in by mail.
On install, the license file also came up with gibberish, but clicking "accept" worked fine. I wasn't so brave with the tax submission.
