Dvbdream stopped working

[trex_daemon]

I have been using dvbdream for a while.
Today i realised it's not loading up any more.
Tried to reinstall, nothing happens.
Driver is ok, it's working with other dvb software

I'm using 4.4.1 b2c2 driver for skystar 2
Op. system is winvista x86
Nvidia 6800 GT video card
nvidia purevideo and ffdshow codecs
(at least i was using them when it worked)

Here's the content of the log file:

What could be wrong ?
When i launch the .exe file, it stays in memory only a second an then it closes without error msg.

At the end i've reinstalled the card's driver and now it's working again
