[R] New version 2.6.1- the menu is written in german

[cris]

Dear all,
i have recently update R in my computer. To my surprise the menu bar  
is written in German language. This is the first time this happen to  
me, usually it is English the language used.
I download the last version from several mirrors from different  
English and Spanish spoken countries, but the result is the same; when  
opening R, the menu appears in German.
Can someone tell me how should i change to English language?
Thanks for your help,
Cristin García
