I have a problem I can't seem to get around. I've created a project in Eclipse (I recreated it from another project that I thought was corrupted). There are no visible errors in any of the files, including the .xml files. However, the project root [project name] itself has an error (red 'x') and so I can't run it. 

On a side note, in the default properties file the line:
target=android-4 is underlined in red with the note that 'android' is not spelled correctly. I have not altered this file since it was generated. 

Any clues? Target is 1.6, sdk 4. And I'm new at this :)
