My niece and I both have the new Windows Live Messenger 2009 (and the Messenger Plus! Beta installed). We both have fun sending silly sound clips, however, since I've installed these mine work, and hers have stopped sending. She can still receive my sound clips.
As an example, instead of sending the sound, it sends "/sound #288A075E3CB1"
I've checked the Messenger Plus! Preferences & Options>General>Sounds tab and all seems ok on her PC. The sounds in Sound Library are all ticked.
I even tried re-installing the Messenger Plus! Beta and it's still the same. Any ideas? Thanks
She had the same problem with sounds last summer, and says they started working of their own accord eventually
