Wrong File Structure for Uploading

OK-absolute novice: in trying to upload the blink code to my Arduino Mega I get the following error:

java.io.FileNotFoundException: /Volumes/Arduino/Arduino.app/Contents/Resources/Java/examples/Digital/Blink/applet/Blink.cpp (No such file or directory)

My current file structure for Arduino looks like this:

Arduino/Contents/Resources...etc.

It looks like there is difference in assumed file locations. Suggestions?

You should drag the Arduino.app out of the disk image (e.g. to the /Applications folder) before running it. This will be more obvious in Arduino 0018.

thanks Mellis-I got it to work. I had dragged it before, but it came across as an alias. Now it is in the apps directory and working fine. many thanks.
