I've been working for two days trying to figure out what's wrong with this thing!

When trying to complete Step 1 it says :
PHP Info
View phpinfo()
PHP Version: Using: 4.3.11 Required: 4.3.0+
MySQL Module: Available: No Required: Yes
GD Module: Available: Yes Required: Optional

And:

Verison
This: 1.7.3
Latest: Connection failed

I dont know why it's not detecting my database and/or why I cant connect. I activated it with GoDaddy, I filled the server and database information into the install.php file, and it still says it's not available. Any ideas?
