I figured it out, but problems still

So I figured out how to reinstall morrowind_ob.esp or whatever that file was that i was missing on my last thread.

I installed archiveinvalidated.

I still have no clue what I'm missing, I re installed everything and am still missing:

"At least one of the core Morroblivion BSA files"

and "Morroblivion ini file"

I do not understand what I'm doing wrong because I followed the instructions on the webpage.

Please let me know!

Thanks
