Can't change language setting on LG Viewty

I changed the language on my LG phone (LG GM360 Viewty) into Turkish, and I now can't change it back. I click on "Languages" in the "Phone Settings" menu but the page doesn't open and I get an error message. The message says "Yürütülemiyor. Bununla çakışma (arama)", which means something like "Cannot execute. Conflict (search)". What does this mean?! Why can't I change the language back?!

Thanks a lot!

that's odd. try this:
create new message > message > "options" icon (bottomest left) > writing Language > choose your language

If that doesn't work you may have to factory reset the phone:
Power the phone up without a SIM.
Key in 2945#*#
Scroll down to RESET FACTORY VALUES
