I thought we would be able to use the dlc once your ps plus ran out. This did happen for me. Can someone help me out
never. LBI gave some misinformation about PSplus and the DLC that they offered.
PSplus is a leased liscence to all the software they offer to their members. ALL DLC, games and benefits are only functional as long as you are still a member for PSplus. When your leased license expires, you no longer have rights to use any of the benefits PSplus have to offer.
The only real advantage to being a member are the discounted deals you get from PSplus. Purchasing a piece of software this way guarantees usage of the software through PSplus's expiration.
When you decide you'd like to be a member again for their service, you are extended entitlements from the last time you used the service, and can use all the downloaded liscenced software they offered you before.
