Like jh mentioned, I would give win32diskimager a try, there were many reported of winimage didn't work well.
Search for the win32diskimager, older version is better for some reason, 0.15 or something. If you can't find, let me know, I'll host the file.
Again, redownload all files, make sure no hiccup in the middle of downloading process.
What you did was correct, just to let you know.
