voip x-lite at vista & xp - errors t61

[m-blue]

hello,
Is somebody using x-lite - viop client on t61?
I am trying to innstal x-lite, and after instalation and trying to start program I have error. I tryed the same on partition with xp but the same error. I downloaded another file from diffrent server, still error. Is it possible that some lenovo driver is making this error?
I try to run file on vista as xp compatible and it is working, but I can't dial any number...
