If you are having problems logging into you moodle installation then you should check a couple of things.
1. Have you typed the Username and Password in verbatim? Case does matter in some systems.
2. Is the Caps-Lock key on your keyboard ON?
3. Has your Tech Support department issued you a Username and Password?
4. Are cookies turned on in your browser?
If you are still having problems you may be able to follow the 'lost password' link in the log on block of the 'send me details via email' button if you are at the login page.
