Help! Spent the afternoon trying to get SugarCRM up and running.

Here's my setup:

WinXP
Apache 2
MySQL 4.1.7
PHP 5.1.1

When running the install, I get a blank page right after Step 3: Database Configuration

Strangely enough - on Step 2: System Check Acceptance page - I have "not available" in red written on the "MySQL Database" line. Could that have something to do with it?

(Please note, I am running MySQL v4.1.7 and have many other apps running, etc. So MySQL is running fine for other websites/apps on this box - not sure why I'm getting that "not available" message in red?)

Thanks in advance!
