It may not be possible to get aldente working.

I'm finding that every time I restart ardent on 1 machine, it deactivates the license on the other.

Looking at the logs, there are 2 files in /Users/spuder/Library/Application Support/AlDente

• 647568.padl
• 647568.spadl

Whenever a setting is changed those 2 files get updated.
