I know this is kinda like a number of other problems that people have had, but I think it's different enough to warrant its own topic..
I've just recieved the ARC E-mail asking me to load revelation onto Arnmour's (or however you spell it) server...the problem is that, never having played though the plot before, I didn't know they would send me a file (revelation), so I didn't clear any space in my completely full memory to accept it.
So now I'm left with the ARC mission that I can't do because I don't have revelation, I can't do the alternate Arnmour mission because I don't have revelation, and I'm just basically stuck...
Is there any way for me to get ARC to send another copy of revelation, or otherwise acquire one, or do I just need to start over?
