technotrend s2300 CI not working

i've got a technotrend premium s 2300 with CI premium technotrend and pcmicia viaccess
and the latest progdvd version.

each time i use for free chanel it works fine, but when i try an encrypted chanel it does'nt work.
when i look CI information it"s written : waiting inofmation....

i'v read a lot of topic about CI in the forum but never found solution yet..

for information this equipment works very welle with original software from technotrend
