OSCommerce

I need instructions, the more detailed the better for installing OSCommerce on Hostgator here.

I have already installed the OSC version from Fantastico as a 'test' and it works fine, but for some reason I cannot seem to access my admin panel.
I dont want to spend much time on the Fantastico version, as I have my own OSC website, developed on my own machine with a LAMP server (XAMPP), that is 90% functional, including its own databse conversion tools, and heavily modded, and now I want to take this online, hash out the last of the 'bugs' and bring this live.

I see the fantastic version is dated 2010, but mine is originally from 2008. If there are any search and replaces for deprecated functions a list, or a poiter to a script would be much appreciated.

I'm on shared hosting, Commercial.

Are we allowed to run scripts here?
I got a 'jailed' error just trying to run a file count script here!

I am somewhat familiar with WinXP, Fedora, Ubuntu, Mint and Mandriva, but havent a clue to CentOS!

I did google a page that looked promising only to find it was removed :(:gatorbang:
