Just set your clock back to the 14 day time period of when they were installed before launching Illustrator CS6. The plugins rely on timestamped files under /Library/Application Support/
They are not located under Library/Application Support/Astute Graphics/, but you still need that folder there. If you move any of these files out of Applications Support, the trial expires. Place them back in, the trial echo's the how many day left till the trial expires. Change the date to anywhere before the install or after the 14 days from the install, plugins expire. Change it back and it's active again.
Not sure if this is for the other products under Astute but I would guess it works the same. So best to install all at ... or you will have some that work on day and not the other.
When the 14 days is up, change your clock to be within the period before Launching Illustrator.
Not a permanent solution but it works.
