Well...let us start with the usual questions that need answering.... Are you using Windows, If yes what version, and where is Morrowind installed? If installed anywhere inside the dreaded "Program Files" directories, the very best solution is to NOT install anywhere inside the dreaded "Program Files" directories. C:\Morrowind, C:\Games\Morrowind, C:\Steam\steamapps\common\Morrowind (Steam users) are all popular places to install the game that avoid a large majority of Windows related issues.
