As a follow-up to my post...

I tried to re-install everything from scratch, except for the mp3 files... and still get the very same error code... (mp3_decoder.cpp ... error=0xc0044000) at the end of the bootstrap, where I guess the player booting gets stack...
The music comes out of the player anyway... but no trace ov Viewer on the Hijack menu list... Sigh! :-(

Has anyone ever encountered my same problem?

Thanks,

Alberto
