Hi to all!!!

I have installed a sound blaster x-fi in my pc and although the sound
quality has been improved incredibly contrary to my old one AUDIGY
PLAYER at games, at music, at movies and generally at the whole sound
system,nevertheless, it shows a problem with the msn messenger 7.5.
While i run the audio set up wizard and i choose the right exits
through the mixer of the card and i listen from the speakers or the
mic either from the reception of the card or the front panel, whenever
i try to have a video conference or communicate only by sound, then i
don't hear a thing, neither me nor the person i talk to. Also, the
settings of the sound on the conversation window are deactivated and
checked with a red ban.Moreover, the movement on the camera is too
slow and the conversation status on the msn has an exclamation mark
which is attached to this message. Does anybody know what this
exclamation mark might mean? I have used skype and everything there
works just fine..when i put my old audigy player card there's
absolutely no problem.In addition, when i uninstall the 7.5 messenger
and use the 7.0 everything works well.

Has anybody any idea what might

be going on wrong?
