Fast but dangerous "fix": Open area in Noggit Rev 94 and save each of your ADTs. You should now be able to open them in Taliis. Open and edit whatever you wanted to edit with Taliis, and save and exit. Now go back into the Noggit you usually use. Edit all ADTs with 0 pressure in Raise/Lower, and Save, Exit and start Noggit again. Now you should be able to work with it normally
However I cannot guarantee this wont create any problems. But that is how I have to do it. But as Steff also said, I highly recommend helping updating Taliis instead, if you know any Java.
But I don't so... "You gotta work with what you have" :p
