At the bottom, Omar Kendall says how to avoid the error screen. Go to your Ps3 settings and update to the latest firmware 4.31. This firmware was optional, but to do cross-buy, you need it.
After that, you should no longer get an error.
don't worry about it. As long as more people are online with vitas, such as myself, I'm happy. I need some friend requests for this game lol
Add me, man! I have 35 people from the forums added. One more would not hurt!
