Protools error at launch

I'M running the version 10.3.10 on MAc 10.6.8

I upgraded protools from 10.3.2 because i had the same problem.



i have clean the preferences, clean the PRAM, clean the computer with disk utilities.

And the same message error appears again and again.

error messages are:

basic_string::S_create

Then PT stops launching.

I REMOVED ALL PREFERENCES FROM DAE, DIGISETUP, PT, ETC. same problem repeats even after new installation

Is somebody encountered that in the past. Could you help me resolving this problem. thanks
