I also found and deleted a plist file in my Library. Now, if I reinstall from the dmg files, I still get the "looks like we hit a snag" window, but it asks for and installs the update, and opens my return properly.
But if I quit and re-start, it crashes.
However, if I delete the plist file before I re-start it, I still get the "snag" window, but it starts up successfully.
It's clearly all about the plist file. I have a little script to remove it, and if I run that before every time I re-start Turbotax, it starts successfully - but still gives the ""looks like we hit a snag" dialog.
