Direction Problems

[Moderator Note: Topic title amended. Your problem is no more urgent than anyone else’s.]

This is urgent because i am on a time crunch.

Okay so i am designing a site for a client, and something very small and stupid occured. The host is laughing squid, and the domain is through Hover.
I had laughing squid do the install for wordpress, which they did using a test link. The site came up fine with the test link http://www.formfunctionllc.com.php53-7.dfw1-2.websitetestlink.com/
(as it should of).

I then tried to change the url to the actual url (formfunctionllc.com) instead of the test url and at first it didnt go through. it just comes up as hovers default page that says “this user does not have any redirects”. Well i let it sit for a little while since i know it can take up to 24 hours for everything to settle.

In the morning, the actual url still wasnt working, but if i put http://www.formfunctionllc.com instead of formfunctionllc.com then it worked.

I was then able to log in to the admin and i went back to working with the products and themes, i then tried to install a plugin and suddenly nothing worked again. It booted me out of the admin and i couldnt go to either http://www.formfunctionllc.com or formfunctionllc.com

the admin for the site is
user: [redacted]
pass: [redacted]

Can someone please help me out here!
Thanks
