Used exceptions to handle errors on InitData(). I hope I didn't made

stupid errors, since I don't use exceptions usually. Feel free to beat 
me on this. Moved uninitialization to _DisposeData(). Corrected some 
styling issues pointed out by axel. Used fprintf instead of printf.
Turned off debugging.
