Hi Crash.

I'm not a guru, so take this for what it's worth.
Check your server information. You must have php 5.2.1 or later and MySQL 5.0 or later for this IDE to work.
I believe that mysqli is available on php 5. To find what you have, use the phpinfo.php call from your browser. It will show you what version you have available.
If you find that you do, indeed, have the required php/mysql installed, post back for more assistance. If you do not have the necessary php/mysql installed, then it won't work on that server.
