Main Ecrypted LVM not Accessible after Deleting a Different Encrypted LVM on USB Drive - Ubuntu 10.10

I installed Ubuntu 10.10 64 on my laptop with the entire 500gb setup as encrypted LVM. So, when the PC is turned on it prompts for the password to the encrypted volume before booting. This has worked well for several months with no problems. During this time i have been backing up the data (450gb) to an external usb drive (1tb) on a regular basis. The usb drive was not encrypted. So, I thought it would be a good idea to encrypt the backup drive too. I wiped out the backup drive and set it up as one large encrypted lvm and mbr. Then I decided to erase that and set it up as encrypted lvm guid. I couldn't delete it while logged into my desktop so i decided to do it from a bootable gparted. In gparted i erased the backup drive once again and planned on setting it up the way I wanted once I was logged back into my ubuntu desktop. Now I cant boot into my desktop with the following errors int he attached pics. When booting from a live version of ubuntu the 250MB boot patition is recognized and 500 partion is there but it is labeled as empty/unused.

The second pic is what pops up after waiting about 4 min. Intial Error Second Message

Someone on the Ubuntu forums has been helping me and has concluded the encrypted partition is corrupt and therefore not recoverable.
