How do I keep what I have?????

I didn't think I did upgrade it - does that happen automatically? I've been using acrobat for years. Never specifically upgraded from X to XI - does that happen automatically when you have a cloud version?  My previous subscription was for all tools, but I am finding that I only use 2, PS and AI, so when my subscription expired ((which I discovered because Acrobat actually told me)) I changed to just the two programs. But now it keeps telling me I have to buy acrobat, too, which I use more than anything else. When I first signed up for adobe cloud acrobat came with the subscription... that's why I wonder if it updated automatically? I would GLADLY revert back to X if I didnt have to pay for the monthly version! it's frustrating!
