Warnings in-game are not caused due to scripting errors. Most likely causes are invalid objects (for example, creating an object with a vehicle ID), vehicles with invalid tuning mods (cheaters can do that, unless you have protection against it), etc.

Try searching that warning on ****** (or any other search engine), you will probably find the reason of that warning. "SA-MP warning 0xC000 blah blah".
