Hi Zukin,
Does it actually say bad passwd? or does it look like it worked but then you are not actually logged in. If its the later one and you are using IE 6 then try this.
1. Start Internet Explorer
2. Go to
http://www.offroadexpress.co.nz
3. Go TOOLS - INTERNET OPTIONS
4. Click the PRIVACY tab
5. Click the EDIT button down the bottom
6. Type ath.cx in the ADDRESS OF WEB SITE bar
7. Click ALLOW
8. Click OK
9. Click OK again
10. Log in
failing that try enabling cookies if they are not enabled.
what web browser are you using? you can find out by going help->about in your web browser.
If its a bad passwd thing I can change it manually for you. Also if its a bad passwd problem sometimes this gets me alot, the capslock key is not on. but from you message I think this ain't the problem.
hope this helps.
Mike
