Error on Boot up of SBS 2008 after installation of RAID Manager

I have recently installed on the Fujitsu-Siemens Server a third array of 146 Gb SAS drives. I installed the Fujitsu Server View RAID Manager so that I can manage and create the RAID in Windows. On rebooting the Server after installation I get the following error message:
"Windows Failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings and then click "Next".
3. Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \Windows\System32\Drivers\AACMgt.sys

Status: 0xc0000428

Info: Windows cannot verify the digital signature of this file."

I understand that the RAID Management software that I installed is causing the problem. However, what I don't understand is that I have installed the same software on another identical Server, with SBS 2008 and it runs perfectly well.

I restarted the server in Safe mode and selected the "Last know good configuration" and the server started OK. However, I need to resolve this issue so that I can manage the RAID on the server.

Any suggestions? Ideas, please?

Thanks

Cypriana

None of the answers solved the problem. I contacted Fujitsu-Siemens and the suggested to updated the RAID Manager program. All fixed when that was installed.

Thanks

upgrade the firmware on the server and the raid controller "off line" prior to installing the RAID management suit.

Although updating firmware is always a good idea, I don't think this is the problem.  The error number is pretty specific. It means that the digital signature is no good.

usually it simply means that either this file is munged, or one of the other files/DLLs/runtime libraries that the AACMgt.sys invokes is munged, or that you have a 32-bit instead of a 64-bit, etc, or permissions issue

I would boot the system to the recovery CD and do binary compare of all files with the other computer, or just do a fresh download and re-install of the drivers.
