You should be able to try again now...they may not have been open when you called (and don't attempt to call on a weekend)

Otherwise, a couple things to try.

1) Microsoft updates were issued this week.   IF something is waiting to be updated with your OS, the TTX software can lock up in certain areas.   Shutdown TTX entirely, and go check for, install, any waiting Microsoft updates and re-boot  your computer.

2)  Wait 5 or 10 min after reboot so that all background operations get started up.

3)  Then Rt-click on on the TTX icon to start it up, but when the pop-up menu shows, go down to "Properties" and click on that.  Then click on the "Compatibility"  tab, then, down in the "Settings" area, click on the box for "Run this program as an administrator"   and OK at the bottom.

4) Restart TTX, and immediately check for a 2016 TTX software update up in the "Online" menu.   then try again.

5)  Still doesn't work?  Repeat step 3 above, but instead, on the same Compatibility tab, look for the "Run this program in compatibility mode for: "  and set it to windows 8 (or 7)......the OK, and try again.

Beyond that....back to Customer Support.

(Dang...you should have bought DELUXE with any states to file.  Don't forget that for 2016 taxes, only mail filing, on paper, by you at the Post Office is allowed))
