It looks like it’s working now! Taking php_domxml.dll out of the php.ini did it.
I’m assuming the charts and such start over when you reboot the system. I rebooted my server, and the historical chart of items added to the library is there, but the play history charts are all blank.
You sir are a good man! Thanks for taking the time to help me out!
So if anyone is wondering, it took some fooling with, but this works on Windows Home Server with IIS and PHP5.
