PT 10 freeze with AirFrequencyShifter

[Bunglespice]

I'm currently a PT 12 user without too many problems but wanted to go back and open several old sessions so I downloaded PT10 so I could access my old RTAS plugs, however every time I attempt to start the program it freezes when loading the AirFrequencyShifter plug and I get the following error:
Could not complete your request because Access violation occurred, unable to read location 0x00000008.
I've looked everywhere on the net to figure out how to uninstall the plug and haven't had any luck. I found it in common files and deleted it but PT still looks for it and freezes it up.
Any suggestions?

My setup is:
- Avid-approved HP PTZ420 Workstation 16gb RAM
- 2 Profire 2626 together
- Windows 7 64-bit
