Ignore the file path in the message, it's an additional info for DICE coders.
And this error is thrown by the game .exe, not by the FH launcher.
My guess is that you somehow ended running a wrong game .exe. Do you launch FH via the FH launcher?
Or perhaps your FH2 copy is outdated. See the FH launcher -> Options -> About -> "Version: ...". If you have the most recent FH 2.47, it should say 2.8.603.
