You will need the following:
1) Internet connection
2) Wired router
3) long enough ethernet cable to reach from your blue ray player to the router.

Step 1:
Eject any disks and turn off the blu-ray player by unplugging it.

Step 2:
Attach the ethernet cable to the router and the other end to the ethernet port on the back of the blu-ray player.

Step 3:
Turn on the blu-ray player and wait for it to load all the way.

Step 4:
Using the remote, arrow over to the left to "Setup", the up to "Network Update".

Step 5:
After the unit updates and restarts, repeat until it tells you "Already Updated".

That should help you play the newer movies, and even some of the older ones.
