I tried to play timeshift demo on my ps3, and ive been playing the demo for about a year now and about 2 hours go it said "matchmaking service is not available" . I want to play online but its saying i cant. i need help!

Maybe a simple question, but do you have a good connection to the internet? If so, then either the game publisher won't let you play the demo online anymore, or the game's servers are down. If the servers are down, you should be able to play the demo within a day. If not, I'm afraid you're out of luck.

If not, the game is just fine, you just cannot connect to the internet. If you need help fixing your internet connection, let me know.
