When i compile my scripts i keep getting

Warning: mysqli_real_escape_string() [function.mysqli-real-escape-string]: Couldn't fetch mysqli in.....

But, when i run the same but non-encoded script everything works fine. I have found lots of entries on the net about this but no solution so far. Any idea what this might be? Any useful links would be highly appreciated. The platform on which i am testing this is the following:

OS: Windows
PHP: 5.2.6
PHP Express:3.0.1
PHP Encoder: 3.0 build 3025

cheers
