What you describe sounds like the Redmine directory of the new version (with just the example files - not any current configuration)!?
Did you move the original directory somewhere else before unpacking the new version? If so, you'll need to get the files from there.
If that's not the case, then it shouldn't have been working at all! Redmine shouldn't work at all without being able to connect to it's DB or without a general config file!
Unless you can find the original files, perhaps you are best off starting again and document each step you take? That way if you hit issues such as this, you can post everything you've done and I will be able to recreate the exact situation you are in on a local server and give you some guidance.
