I did that after the breakdown, Grab. The problem is not anywhere obvious. And no, I am not going to repeat the steps that interfered with my music-making.

I have been editing music files for years - so many years, in fact, then when I started, I had to have a sound card installed specially because sound cards were not normal computer equipment.

Computers and software are still not really ready to handle sound. For example, the technicians that serviced my computer last time admitted that none of them understood how to play a MIDI. And their firm was supposed to be one of the best in town.

Another example - my computer can download, edit and play MIDI files, yet HELP doesn't even know that MIDI exists. My files are played by the Microsoft MIDImapper, yet Help says there is no such thing. In other words, the people at Microsoft don't know what they're doing when it comes to MIDI.

Music sites that offer contemporary pop mp3's are notorious trouble-makers. I wouldn't go near them.

So, if you are happy with your computer, do not fool around with sound. And if you have XP, remember the System Restore feature.
