Can't open 24-bit sessions with 5.3.1

[spudBone]

Here's my dilemma:
I can create and open 16-bit sessions all day long on either scsi MacOpener drives or the internal IDE drive. And, I can also seemingly Save Copy In from 16-bit to 24-bit sessions without any errors being displayed.

However, when I attempt to open any of the 24-bit sessions I saved, or if I try and create a new 24-bit session on any drive, or if I even try and open an existing 24-bit session on the MacOpener HFS drive (a verified 5.1 session used at work), it's a no-go.

I always get the following message:
"ProTools was not able to reacquire the hardware and must now exit. Message ID= -1103."

My setup is as follows:
Ptools 5.3.1 on Windows 2k Pro, w/ all updates
one 888/24 legacy I/O
24|MIX core card
Symbios 8600sp scsi card > 20 mips max setting
Celeron 550 mhz processor, 384 meg ram
Seagate 8.5 gb Barracuda external Scsi drive
Maxtor 20 gb internal IDE drive
MacOpener v6.05, registered
PLEASE HELP.. THANKS.

Well, it's working okay now. Seems that the extra memory I installed (256 meg stick) wasn't seated quite enough in the mb socket.

Now that all 384 mb are being seen the system rocks!
