Issue:
After installing SurferEQ 2.0.5 or SurferEQ Boogie 1.0.5 it still uses the previous version installed (newer than 2.0.5 or older than).
Resolution:
Please manually remove the SurferEQ AAX.
It is located in your AAX Plug-Ins folder:
/Library/Application Support/Avid/Audio/Plug-Ins
This can be accessed by the View menu in your finder and Go to folder..
Note: This doesn't affect Windows.
