Newbie: Can't get my PHP server to work

Hello Everyone: First of all: I've been dealing with PHP for less than 24 hours, so please forgive me if my questions are too basic... I'm using Xitami on a Windows 2000 server. I installed PHP and it seems to be working fine, but then, I tried to add a few file management scripts: PHP Commander - http://szewo.com/php/ and QTO File Manager - http://www.qto.com/fm Both seem to initialize correctly at first, but when I try to use the interface - press buttons to upload files or navigate to subdirectories - nothing happens. I suspect that it is something related to the php server setup; I already tried to change the INI file in my W2000 forder, allowing uploads. My whole objective is to create a public file repository for our company. Please? Any ideas? Thanks in advance!
