Depending on where you are in the world...
1. Report the theft to the police.
2. Is your console currently registered with Presonus? Do you have the serial number of your console? Get your console registered with Presonus using the serial number.
3. Many times, users will post their items they have had stolen on Craigslist (not sure if this is available where you are). This greatly helps with controlling a re-sell of stolen items and/or can help with tracking down stolen items.
4. Open a ticket with Presonus and ask them if there is a protocol they have available to mitigate issues with stolen property.
