Installing Firewire External Sound Card?

I have a HP built box that I purchased less than a year ago. The hard drive died, along with the motherboard.I purchased a new hard drive and the full version of Windows 7 Home Premium 64bit and had the shop replace the MB, Install the new hard drive and O/S.The motherboard is an ASUS M4A785-M, with an on-board Realtek PCIe GBE Family Controller (according to Windows Device Manager).I have a couple of additional cards installed, one is an eSata controller for an external hard drive and the other is a SIIG DP FireWire 800 3-Port PCIe card.I initially installed the SIIG because the FireWire chip set is Texas Instruments, because I have a PreSonus Firestudio Mobile (sound card, recording hardware)and it only plays nicely with Texas Instruments. The SIIG card shows up in Device Manager under IEEE 1394 Bus host controllers as "Texas Instruments 1394 OHCI Compliant Host Controller", which I "assume" is correct?

My problem is the PreSonus hardware refuses show up in Device Manager or initialize (there is an indicator light on the front of the unit that will glow blue when it is connected or flash blue-red when it isn't). PreSonus has a driver set for the Firestudio Mobile, that is called Universal Control.I have attempted to install Universal Control several times, but each attempt has resulted in failure, with the Driver version showing 0.0.0 etc. I realize this is the problem, but I have no idea how to force the issue.If I could get the PreSonus drivers to install, I would be home free (I think).he PreSonus hardware should show up in Device Manager under Sound, video and game controllers, but it doesn't.I have also posted about the issue on the PreSonus forum, but haven't had any solutions posted.This computer and the hardware are what I use to run my Recording Studio and without the Firestudio, I am effectively out of business.I should also note, that I haven't even installed any other software beyond windows 7, other than a couple of utilities. Not even my DAW or the drivers for my peripheral midi devices.
