"eucon personality" recognized by pt11, not by pt10 !

Hi,

I'm getting mad with that trouble : my MC mix works perfectly with pt11 (eucon 3.2, os 10.8.5), but pt10 gives me that message "unable to load eucon personality".

I tried everything, including trash preferences, repair authorizations, uninstall eucon 3.2 and reinstall 2.6 (that worked perfectly on my older daw), with no success.

Any help ?
