How do I get original DJay for Mac?

Where can I get the original DJay for Mac back? since going to the DJay 2 Pro - things are not working? I need to use the older/original DJay until all the issues w the new version are worked out. Anyone know how to get the original application of DJay back?

Hi Paul,
Please open the Mac AppStore, select “Purchases” and download djay from the given list.

The key might be for an older version, not djay Pro 1 or 2. Please contact us via support@algoriddim.com for further information.

How do I get original Djay for Mac if I haven’t downloaded it yet? I bought a WeGo3 and it came with a serial number but I can’t use it on Djay Pro for Mac!
