Thanks
Finally today i decided to buy Transposer 2 for C6 (i have only the version 1 from Eovia)
because the native importer was too buggy according multiple tests conducted today with my installation
For now i find Transposer2 very good  and i like the way all the poser lights is loaded in Carrara pro 6 
I am with you about the job did by programmers (i know by some of my friends how hard is to put all the codes without problem with a complexe soft) I never program my self since the sixties when i have tried it
