Ok mate, lets try this.
Go to
Start |
Control Panel. 'Switch to Category View' and go to Date,
Time Language, and Regional Options. Then choose
Regional and Language Options and be sure to check some settings in there. For example, under Regional Options, make sure that you select your prefered format. Moving on, go to 'Languages' and click 'Details'. It's important to select English as your default input language. And move on to Advanced and again select English. Play with them!
Let us know if this works mate, i hope hehe

Should be something to do with language properties I suppose, so try them and reply
Regards
