Blogger error: 'Try going back and re-trying'

This Blogger error message made me smile (click to see a larger version):



In essence: 'What you want to do has already been done, so try going back and re-trying...'

And I suppose it highlights the difference between 'try' meaning 'test in order to see if it is suitable, effective or pleasant' ("try going back one page in your browser") and 'try' meaning 'make an attempt or effort to do something' ("and re-trying"). At least that was how I read it; I can understand if your reading is different.

Both definitions of 'try' came from my Concise OED, 10th Edition, by the way.
