No other software should be running at the time of execution.

Performance may be altered if you have background tasks (such as a Messenger tool, a virus permanent scan, or FindFast function, to name a few). In most cases, you won't even notice.

Performance may be improved if you reboot your PC before launching the CD-ROM.

If your RAM is less than 128 MB RAM, musics will likely not be executed.

From time to time, if you have a PC with 128 MB RAM, at launching you may find out that you do not have enough memory to play the musics. In such case, select 'Stop', and re-launch immediatly.

The "personal comment" functionality is disallowed if your PC's RAM is below 256 MB.
