I (stupidly) converted a TrueCrypt encrypted disk to GPT in Disk Management: now TrueCrypt won't mount it

Backstory: After moving a Macrium Reflect disk image from my TrueCrypt external drive (with whole disk encryption) onto a unencrypted drive and using Windows PE with Macrium Reflect to restore my internal disk to the recovery image on the external unencrypted drive, my Windows 8 failed to boot. I then went back and also recovered the System Partition (looking now, it is currently EFI), but I still couldn't boot into my backup..

I was in a hurry to get online for something so I just did a clean install of Windows 8, without the backup.. After I installed Windows 8, I went into Disk Management out of curiosity to see if there were other partitions with Windows 8 that Macruim might have missed, and there is (by default) a Recovery Partition of 100MB. My memory of this is hazy, as I was trying to get up and running for an exam at 4 AM:

Something in Disk Management prompted me to convert my encrypted external drive to GPT.. I have no idea why I did this, but I went ahead and allowed it to convert my TrueCrypt drive to GPT. Now, I can't mount the drive in TrueCrypt.. Disk Management sees it as Disk 1, Basic, and Unallocated. I tried converting it back to MBR with Disk Management, but no dice with TrueCrypt :(

If I try to mount the disk in TrueCrypt I get the message: Incorrect password or not a TrueCrypt volume

I should never have messed with a Truecrypt drive in Disk Management, but I did. I have important college work in that drive, and fear I have lost it forever. PLEASE HELP
