How to open a .XXX file??

[RobyLP]

Hi, I am developing a iOS game, with Game Center Multiplayer, multiplayer works great until match ends, then "I Guess", there's an attempt to write leaderboards "ClientWriteLeaderboardStats".
I get an error Log, in iOS Device, related to "OnlineSusbsytemGameCenter/src/GameCenter.mm(1519) Assertion Failed: CurrentMatch == Match"
After this log line UE3SYS Crahes on GameCenter.mm.
The only file that could have "GameCenter.mm" inside is OnlineSusbsytemGameCenter.xxx (a file that is inside of UDKGame.ipa, in the Binaries/Iphone, the ipa deployed to device).

I tryed to use 7z, winzip, winrar to open this .xxx file, but no luck.

Can anyone tell me how to open this file o or post a copy of the GameCenter.mm that Unreal Engine uses?

Thanks!!!

GameCenter.mm is part of the native source code and therefore you do not have access to it. Not sure what would be causing the crash. You'll probably need to provide some more info about your implementation.
