TotSC goes wrong

I have downloaded a patch from interplay´s page, but the problem remains.
The objects´ information (name, statistics) doesn´t appear either. In the map, the scroll shows a number (e.g. one of the cloakwoods is 38, friendly arm inn is 8...).
What is this!!!

I have installed TotSC and I have discovered some problems:
1.- The new maps (zones) don´t appear in my map until I find them (I have heard they should).
2.- When I put the cursor in a zone in the map, or in a person in a new zone (e.g. Durlag´s tower), the scroll where his name should appear doesn´t show anything.
3.- If I talk to a person in a new zone the dialogue box opens and appears empty. There is no "continue", or "end dialogue" button.
4.- When I start the game, it always asks me to insert the CD6.
5 (and last).- When I select single player, under the "load game" button appears a button with no message on it. If I press it, a empty message appears and then the load game screen

Do I need some kind of patch? Where could I find it?
