Just finished Morrowind and installed Tribunal. Do I need to start a new game to play Tribunal and if so, will I lose character stats and inventory?

No, just carry on from your current character

Any particular place to start or just start roaming around?

Just keep playing, Tribunal will make itself known to you very soon.

So far it has been 12 (in game days) and have tried talking to all kinds of people and resting and haven't heard of anything. I guess I will rest in real time for a while, then try again. thanks

Rest more than once. The chance for Tribunal to "make itself known" is random.

Well I loaded the Bloodmoon expansion and patch and now I get error msg that sez-- Failed to load Snowflake:Meshes\BM_Snow_01nif I get this everytime I hit play at the start screen. I am not a computer whiz and do not know what to do. I have left question with gamesas but no response so far. I am a level 29 spellsword in Morrowind and really don't want to lose my saves. Can anyone HELP????

Do you still have a save from before you installed both expansions? Or even just Bloodmoon?

When I look at the data files in the start game screen they are still there, I just can't get to them.

Are the expansions activated from the startup launcher? You should be able to tell really easily if Bloodmoon is installed correctly and active, because almost every NPC in the game will have a line of dialog about Solstheim (which is serious overkill). Tribunal (which MUST be installed before BM) may take a while and a few nights' sleep to make its presence known.

The error with the missing mesh or texture may mean that the expansions, or parts of them, are installed in the wrong folder, and the game can't find them.
