Ok, I figured out how to get my drives unencrypted. It was a long process of trial and error, but I am decrypting the files as I write.
1- comodo does not work if you have your boot drive on a raid. I had to install a new hard drive and turn off the raid in the bios. After that, your password will work and the system will boot.
2- You also have to disable boot sector scans from your antivirus in order for the comodo disk encryption error to go away. The antivirus suspects a boot sector virus and blocks comodo so you get the encryption subsystem error. I use ESET NOD antivirus.
3- once these two factors have been dealt with, reboot and enter the password at the boot prompt and you should now see the drives in comodo disk encryption software and will be able to decrypt the drives.
I hope this helps all of you that have the same problem...frustrating as hell and makes you cranky
