Can't log in to my admin dashboard

We are having problems with our WP site (xtremeactionpark.com). I can't log in as admin, and when I request a new password, the link I click on sends an error. The listed inmotionhosting password isn't working for our back-end guy. The registered e-mail is [email protected].  The password listed on my sheet is 5300@Xtreme33309 but when I enter that info I get the following error.  Invalid e-mail address and/or password.
