thanks for reply guys and forget everything.
I just got it
I got another copy of q3a and configured everything again and it works now
so, maybe there was a file missed or something like that, I can't say.
Yup, the correct location for entities.def is q3a/baseq3/scripts
and the correct location for defrag.def is q3a/defrag/scripts
Well, I return with my projects.
I'm so embarrassed, but anyway
