Problem with Html Tidy

Hi there,

I've used html tidy for a few days and it was wonderful, 
Suddenly it didn't work anymore, I'm getting this error message :

Error: tidy.php requires PHP 5 with libtidy support built in.

I use windows 7, IIS7 on my computer with PHP v 5.3. , extension=php_tidy.dll is enabled, There is no problem with the local server, it works without problem.

I've tried to reboot, re-install html tidy, fresh install of Sublime text 2 , restart IIS 7 , nothing help.

The path to php folder is already in environment variables PATH of windows.

Any help is much appreciated.
