Simple Drawing App crashing on launch - was working :(

[marshusensei]

Im hoping somebody can help me. I don't know why this is no longer working for me... can anyone make something out of this crash log:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/marshusensei/Library/Application Support/iPhone Simulator/4.2/Applications/A10938B2-D19D-4C92-A3B9-95B4C7C68DCF/Simple Drawing.app> (loaded)' with name 'MainWindow''

terminate called after throwing an instance of 'NSException'

Any ideas what I have done wrong?

Thanks in advance

Have you changed the names of any of your Xib files recently? Take a look at the code in your App Delegate and check to ensure that the Nib that it's trying to load post-launch, is definitely available in the bundle.

That's my thoughts anyways... I'm sure someone with a lot more experience will be along shortly to offer some better advice!

Thanks James, I've messed around with it a bit too much, it's a bit of a messy app now. Decided to start again. Appreciate your advice.
