i can't find the 2014 versions of the books i purchased in my library.

What happened to them?  If i can't access them, i don't have any incentive to continue my subscription.

I still have mine. I would try syncing your Entitlements on your profile. 

My Account > Licenses. If there is anything out of sync, there will be a button you can click to re-sync them. 

If that doesn't work, check to make sure you didn't make your purchases on a different account and if that doesn't work, open a ticket with customer support. 

I've still got my 2014 boks showing up in library too

I had a similar issue. After a bit of ranting I realised my filter was set to 2024 rather than All. Ooops...

it says i'm "in sync", and that i have 20 purchases.  However the screen only shows 10, and none of them are the three core 2014 books.

Edit: I tried adding a screenshot, but this forum doesnt seem to like that

 You'll need to host the image somewhere else and then embed it using the insert image button

Have you checked your library filters? And what happens if you go to any of these links:

• Library: 2014 Official Sourcebooks
• 2014 PHB Introduction
• 2014 DMG Introduction
• 2014 MM Introduction
