If you have PS2 downloaded via steam go to your steam library, right click on ps2, properties, local files and verify integrity of game cache. Wait for this to verify then if it says missing files, just accept the option to redownload the missing files. This may take 1 hour or above depending on your internet speed, mine takes about 1 and a half hours at 1.6MB/s. I hope this helps you guys because I had this problem for a while until I found a fix, kept me from playing my beloved PlanetSide 2 for about an hour. </3
