   I'm just starting out with cocos2d and working with some tutorials to construct a simple App with Cocos2d that displays an image. But the App crashes immediately on load.

   This is the file implementation file for the scene I made that has the image.
   

   #import "Main_Menu.h"
   #import "Sprite.h"
   #import "cocos2d.h"
   
   @implementation Main_Menu
   
   -(id) init
   {
   	self = [super init];
   	if(self != nil)
   	{
   	Sprite *background = [Sprite spriteWithFile:@"Main_Menu_bg.png"];
   	background.position = ccp(240,160);
   	[self addChild:background];
   	}
   
   	return self;
   }
   
   @end

   #import "Cat_TrapAppDelegate.h"
   #import "Main_Menu.h"
   
   @implementation Cat_TrapAppDelegate
   
   - (void)applicationDidFinishLaunching:(UIApplication *)application
   {
   	UIWindow *window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];
   	[window setUserInteractionEnabled:YES];
   	[window setMultipleTouchEnabled:YES];
   
   	[[Director sharedDirector] setPixelFormat:kRGBA8];
   	[[Director sharedDirector] setDeviceOrientation:CCDeviceOrientationLandscapeLeft];
   	[[Director sharedDirector] attachInWindow:window];
   
   	[window makeKeyAndVisible];
   
   	Main_Menu *mainMenu = [Main_Menu node];
   	[[Director sharedDirector] runWithScene: mainMenu];
   
   }
   
   @end

   I'm using the latest version of cocos2d and I'm not receiving any warnings or errors. I'm new to all of this so any help is appreciated.

   You should get some sort of error in the console window when running.

   Sorry I did, didn't see it at first... but still left a little confused

   2009-10-16 12:43:54.386 Cat Trap[5419:20b] *** Assertion failure in UIApplicationMain(), /SourceCache/UIKit/UIKit-963.10/UIApplication.m:1069
   2009-10-16 12:43:54.387 Cat Trap[5419:20b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Unable to instantiate the UIApplication delegate instance. No class named Cat Trap is loaded.'

   )

   I'm following a few tutorials at once and probably messed something up when setting the project up at first, but not sure.

   UPDATE: Now seeing the error I figured out my problem

   #import <UIKit/UIKit.h>
   
   int main(int argc, char *argv[]) {
   
       NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
       int retVal = UIApplicationMain(argc, argv, nil, @"Cat_TrapAppDelegate");
       [pool release];
       return retVal;
   }

   I misspelled Cat_TrapAppDelegate
