I had to reinstall a copy of moodle 1.9 (because I did something stupid - can move on?) and, to my relief, the list of courses was still there - presumably in the SQL database which was untouched. However, my admin password no longer works; nor do any of the other passwords. Is there a way of doing a reinstall that won;t have this effect, or will let me set an admin password - preferably without having to upload all the files again?
