CI Tutorial + TextMate = Error, please cache your project first.

[eluser]Unknown[/eluser]
Hello everyone,
needless to say I am entirely new to Code Igniter, coming from the ExpressionEngine CMS (1.6.8) I wanted to look into this framework for simpler non CMS website I build so I started reading the User Guide and following the tutorial but my TextMate keeps bugging me about "Caching my project first" whenever I try to write a '(' symbol.

Does anyone know what is going on here?
