Help with Configure.php files

[gulpgraphics]

Hi.

At the moment my website is www.cheekymartini.com

 

I am moving hosts, to a business package, as the server Im currently on isnt going to provide me with the facilities for multiple sites unless I paid quite a lot of money.

 

I am wanting to transfer this site across and keep my products, customers and everything intact.

 

What I have done so far

 

I have backed everything up.

Set up a addon domain and created the subfolder with the new host

I have then uploaded the contents of cheekymartini site to the subfolder for the addon domain

I have imported the database

I had it to the point where the site was loaded, admin wasn't working, and the database wasn't showing on the site. I have read a few tutorials in previous posts that i searched for on what to do with the admin/includes/configure.php and /includes/configure.php I tryed to follow the tutorials but now to the point where the site doesn't load haha

 

I was wondering if anyone could help me, either on here or through msn. PM me for my contact details.

 

Thanks

One other thing,

the admin isnt working I get an error saying 500 Internal Server Error. I thought this was to do with my configure files.

 

Ive done a fresh installation witht he global registers fix, on one of my other domain names, and I get the same error when trying to access the admin area. Any thoughts on that?
