For the most part, do agree with Derek ... but, is there a recent site backup ... ie, sql dump, tar ball of data directory?
Could restore those to a sandbox site with approximately the same version of Moodle code and be able to recover the course that way ... although it probably would NOT have anything new added since the date of the site backup.
Sorry, but through pain we all learn. Most of my server 'expertise' comes from past 'painful events'. :|
