I just want to know what happens to my data when subscription expire. Can I stille read the files?
You still have your data file and basically you can continue to use Quicken and to see your data. You can only make manual entries to your data file. You can no longer communicate with your Financial Institutions nor get Quicken updates and etc. etc.
I have not seen it but I hear there is a pretty nasty NAG SCREEN you have to put up with by having an expired subscription.
Why do you want to let it expire?
