Downloading the file, extracting the BSA and .esp, and then registering it automatically via the BSA Browser/Registrar.
For some odd reason this time, when I tried to register the BSA file through the browser this time, it comes up with the message that all morrowind bsa's are all properly registered. I initially thought that maybe this was right, but as soon as I entered my game, I started seeing those classic screen warnings of missing .nif files and marker replacements being executed. I don't know how to get around it, and I never found an article that taught me how to manually register my BSA files into the morrowind.ini
I can tell you guys that recently, I did use the TESTool to merge some .esp's because the initial warnings when I started the game got on my nerves.
Bottom line is, any help or pointing in the right direction is much appreciated and I thank anyone who contributes any input in advance.
