PT 5.3.1 will not load drivers - HELP!

[lexluth]

My PT 5.3.1 has been running fine up until this evening. When I try to launch Pro Tools, I get an INITIALIZATION ERROR. It says "This software requires installation of certain device drivers and a reboot before using. Please reboot or re-install the software."

I've rebooted several times, ran PT setup and chose "repair" option, and I've even un-installed and re-installed the software, but cannot get past this error message.

Digi Wavedriver is working O.K.

I'm running a P4 2.53 @ 533MHZ FSB, 1.0 GB Corsair 2700 RAM, ASUS P4PE BP Motherboard, Win XP, Antec TruePower 430W power supply, (2) WD 80GB HD's with 8MB cache on a Promise 133 TX2 IDE controller card. I also have an ATI 8500LE video card and the on-board LAN & Sound disabled.

I have not installed any new software that may be conflicting with the Digi001.

Please Help.

Thanks in advance.
