Spetsnaz

Hello, So I had purchased 911: First Responders. After being unable to play online with a friend stating "mismatched files" even on fresh installs, I purchased EM4 hard disc version. The same version he has. Installed the game. He states his says 1.3 EN. However upon install my game continues to say 1.3f US. The menu is bugged complete. (ID_TEXT) on all the text. I have deleted the 911: First Reponders install file, and everything, uninstalled...reinstalled...done numerous things and nothing. Please help!

Hello, So me and a friend have been trying to play this online. I have 911: First Responders and he has Emergency 4 English. We tried several times but could not get it to work. We are able to connect but it states Checksum: files differ. Or something similar. We both have done complete reinstalls of our games and it still says the same exact thing. Can someone help us out here?
