aamfp.exe caused an EXCEPTION_ACCESS_VIOLATION in module...

I don't think so because I've seen others with that error message who claim it didn't crash, but we can try to fix it anyway.
It should be an entry within the english.lang file in the config folder. The game can't find it so maybe it's not actually there, but it ought to be.

If you use ctrl-f or so in that file (open with Notepad++ or similar) then search for WelcomeMessage04 or 01. Copy that line (including the opening and closing tag) and rename it to 05. Save and see if it helps.
