Here is your solution. You're welcome. I'm welcome.
1. Decrypt your OS hard drive completely.
2. Re-boot your Mac and during the re-boot process hold down <cmd> R. This will bring you to the Recovery menu for Mac. Select the option to reinstall the OS.
The Mac will connect and ensure that you are licensed to have the OS you are asking to re-install. It will prompt you to enter your iTunes information to access your purchase history.
The next hour or so is spent with your computer keeping it awake as it downloads the 4+GB of new OS.
3. In your new OS open PGP WDE.
3.1 BACK UP YOUR PUBLIC/PRIVATE KEYPAIRS ON A CD OR THUMB DRIVE. (not your computer)
3.2 Back up your public/private keypairs. If you skip this step, proceed to throw out your HD.
4. Select "About" and then select "Uninstall" (make sure your encrypted non accessable hard drive is not attached. PGP will not let you uninstall while it recognises the encrypted HD attached. "But it doesnt show up in my PGP control panel" you say? Yeah, I know. Somehow, in the back of PGP's mind, it still kinda knows there is something there)
5. MAKE ABSOLUTE CERTAIN YOU HAVE DELETED THE FILE Users>User>Documents>PGP
6. There is a tech document on Symantec site somewhere that gives the scripts to run in Terminal to manually remove the PGP files (there are a bunch of stragglers that can jack up your clean re-intall)
You now have a clean install of the lowest version of your OS.
PGP is nowhere to be found on your system.
7. Download the earliest version of PGP from Symantec portal that is compatable with the OS you are now running.
8. Install PGP. If you did this correctly it will prompt you to create a new folder for your keypairs.
The formerly not-recognized hard drive should now be happily displayed in your PGP control panel. You can not decrypt it yet though. You need to have the secret key to unlock the encryption.
9. Import the keypair you saved by going to PGP>Preferences>MasterKeys.
use the + icon to add a keyset. Drag and drop the saved key into the proper side of the menu. Add the key.
10. Decrypt your drive using the passphrase you KNEW you did not forget.
11. (optional) After updating your computer back to the state you had it in before the chaos ensued, it is entirely up to you to re-encrypt with software that is clearly not backwards compatible or scenario tested before updates are released.
12. (manditory) Decrypt every goddamn drive you have prior to changing anything. Do not trust that any software is compatible or has been thuroughly tested for compatibility.
13. (optional) Write to Symantec and recommend that their project manager for new releases be executed seeing as every OS update takes months to patch, and then months more to debug.
