unable to access wordpress site

I stupidly moved my wp files from the folder (webblog) in which they were resting, to my main website folder. The whole thing crashed. So I moved them back to the webblog folder. The website (www.being-in-voice.com) is back, but the blog site (www.being-in-voice.com/webblog) just returns error messages. So I cannot even login, to redirect the url, which is what I should have done in the first place.

Any advice or assistance would be most welcome. I’ve just spent 3 days revising, editing and re-creating the blog. I assume a fresh installation would lose all my changes.
