Today My Computer Stopped Playing FFXIFollow

I've been playing FFXI on my laptop for the better part of the last year and today it started giving me this error when ever it switches over to full screen:

"Terminated as error occurred in FINAL FANTASY XI. Failed to initialize Direct3D. Please check that this computer has the required specifications to run FINAL FANTASY XI. (-1)"

Now I know what this means... That for some reason FFXI started thinking my laptop isn't capable of running it anymore. But all of my other D3D (and OpenGL) games work just fine.
Any ideas?

HP Pavilion zd8020EA
Windows XP Media Center Edition
3.0Ghz Pentium4 (Desktop Version of CPU)
1Gb Ram
Radeon Mobility X600 with 128Mb Ram

Edit: Things I've tried to get FFXI to run again
Re-Installed Video Drivers
Re-Installed DirectX
File Checked POL
File Checked FFXI

It's a sign. Telling you to quit playing now, and go outside and get some fresh air and sunshine. Trust me on this.
