We really can't say much if you don't send us the TeX source file that you were compiling. Something's happening at line 53 that makes Babel load the language "nil", that's about all we can say.
Also, since your hyphenation patterns are clearly correctly installed, you may have more luck looking for support on generic TeX mailing-lists or fora such as [email protected], or tex.stackexchange.com. Arthur
