That's awesome! I'm glad it still works. I stumbled upon this work around 5 years ago when I was in college and Adobe quietly switched my subscription from the student version to the full CC suite. I contacted support because I genuinely couldn't afford to pay $60 a month and support was no help whatsoever.
How did you get the above mentioned 14 days to pass in 40 minutes?
You need to cancel BEFORE the 14-day period, after that you’re locked in again.
