I feel like I am totally missing something. 

I'm having trouble installing Tamriel Rebuilt. I am using OpenMW on a Mac. 

I download and extract everything and register everything in the ini. Problem is, that the two BSA files that I have to register, are not even in the downloaded file? And as such, I have huge missing textures everywhere. I seriously do not get this. Any help would be appreciated! 

(I am talking about the PT_Data and TR_Data BSA files, which I can't seem to find anywhere) 

Thanks!
