Install Woes - Error Messages Enclosed

Some background:

I've modded Oblivion before but I'm not very good at it.  I don't know if I'm even providing the right info, or if this is answered elsewhere.  I spent about an hour looking before posting it but couldn't find this exact problem.  Apologies if what I'm providing is insufficent, or if I overlooked an existing answer. 

System: 

I'm running windows ten, and I installed steam outside of the program files folder in order to avoid UAC issues with Oblivion.  It is on the same drive as the operating system, however - maybe that's the problem? 

Game: 

I'm using Mod Organizer and Wrye Bash, and I installed the mod and its requirements following the official install instructions from this site - well, to the best of my ability : P.  I have not installed any other mods. 

I have Morrowind and Oblivion and their expansions installed.  

The error message / problem: 

Well, first of all, the game works but it's just normal Oblivion, no signs of the mod.  When I start a new game, it starts a normal game of Oblivion, and I get an error message saying that "Morrowind_ob.esp is not loaded."  A screen shot of the error message is attached below.  This confuses me, since it appears to be installed in Mod Organizer?  I must have done something wrong, but after hours of trying different things, no luck : (.  I screwed up something somewhere, but I just don't know where ... any suggestions?  

Thanks for creating this mod, btw!  I haven't played it yet but it looks awesome, and it's one of the reasons I bothered with Oblivion again. :D 

Edit - 

Eh, I'm dumb!  It does in fact seem like the .esp is missing.  It doesn't seem to appear in the Oblivion data folder when I run the installer?  Not sure what to do there.
