You have the games in your library, but you can't play them.
If you will re-subscribe a PRO membership you will be able to play them again.
If you bought them, you can always play, even if you are not a Pro
@wwjoshdew any games you buy, even with a Pro discount, will be in the store library labeled as "Purchased" those are games you own and will be able to play whether you pay for the Pro subscription or not.
The "free" games that you claim are in the store library as "Claimed" and can only be played while you're a Pro subscription member.
