[tex-hyphen] No hyphenation patterns found

[stehlampen at arcor.de]

Hello,

I´m using MikTeX (recently updated), XeTeX and the language "german". If 
I load the language with Polyglossia, I will get the following errors:
Missing number, treated as zero.
<to be read again>
                    \l at german
l.124 \begin{document}

Missing number, treated as zero.
<to be read again>
                    \l at german
l.20 \select at language {german}

Package polyglossia Warning: You asked for `ngerman' but only `german' 
hyphenation is available! on input line 57.


followed by some overfull hboxes.

Because I knew that it´s a bug in polyglossia 
(http://tex.stackexchange.com/questions/98270/faulty-output-because-of-polyglossia-issue) 
(How can I send a bug report to the maintainers?), I´ve examined the 
languages.ini. For the language german, the entry is:

[german]
loader=loadhyph-de-1901.tex
lefthyphenmin=2
righthyphenmin=2
patterns=hyph-de-1901.pat.txt
hyphenation=hyph-de-1901.hyp.txt

My problem: The hyphenation file hyph-de-1901.hyp.txt contains 0 Bytes - 
it´s clear that LaTeX can´t find hyphenation patterns. I assume that 
somewhere, LaTeX is sent to a false file. Could someone help me?

Many thanks in advance.!
