I have a Nano and I am working on a project right now, ive written code that works, but when I upload it I get this error code:

Sketch uses 3342 bytes (10%) of program storage space. Maximum is 30720 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Also, don't know if its worth mentioning but the Nano itself got very hot while uploading it.
