Several things to try:
1) you indicated that you have the updates....but...did you check the Windows updates? Those can block proper operation of TTX.
2) Try to rt-click on the TTX icon, an select Run As Administrator.
Still no go?
3) Try to download and install the "Manual Update" . Once you get it going it takes 5-10-15min to complete. (But if it indicates you already have the proper ones....it may not do anything)
