i have made some testing reinstalling and tryng to understand where the problem is
seems not to be injection the problem but the client 4.0.0c
here are the steps
if i use the client of my shard 4.0.4t all go okei
if i use the client 4.0.0c (with or without injection is the same) the character stops speaking
and from now on with any client i use (even the original of the shard) not only che pg does'nt speak but the text does'nt appear ons creen when i write...
copyng the files of the just-installed version (i made a backup) and using the cleint of the shards turn it to normal
client 4.0.0c adds some files in the uo folder that other clients don't add

strange thing
those files are:
two .mul (don't remember names on the mai uo folder
an uo.cfg in every pg folder
and a multicache file in the main pgs folder
even deleting those files the pg does'nt speak
