Widespread software piracy has made this system necessary. Pirate websites are numerous, and very popular. Just google “salsa rhythm machine serial” and see what comes up. Without an anti-piracy system, development and support of this product would have ceased years ago.

When you play the first song, Salsa Rhythm Machine will try to verify your username with my server. This usually takes less than a second.

If you are using a firewall, such as the one built into Windows, you may need to configure it to allow access to trivisonno.com.

After a failed authorization, you will have to restart the Salsa Rhythm Machine.

If you still have problems, email me the contents of the ‘auth-debug.txt’ file. To find this file, go onto the Salsa Rhythm Machine’s “Help” menu and then to “Open App Data Folder”. On the Mac, you can just go into your Salsa folder. Once you have the file open, paste it into an email, and send it to the email address on the About page. Also include in the email the email address and registration key that you have entered into the Salsa Rhythm Machine.
