Judging from the file name, I am guessing this file store the text for all object names/properties etc in different languages.
If you don't mind doing a bit of troubleshooting -
Double check your control panel -> regional settings, ensure you only have the language you want there.
There's also a setting in the EC to always display item name (or was it properties? Can't remember offhand) is english. Check what is your current setting and toggle it.
Exit EC and save settings.
Move this file to a different folder (outside your EC client folder), then restart EC, tick the "check all files" box and let it recreate the file. If it doesn't, probably means it gets generated on the fly after you login. So try logging in and playing a bit to see if you encounter any problems.
If you would rather not do anything in case it might cause other issues, go to EA's knowledgebase/tech support site and open a case with technical support (just to clarify, I mean the technical support page. Not in-game GM). Let us know how it goes.
