Central Computer Room

[coolcatkelso]

Hi again

Need help (again lol)

I'm in the main central computer room, gave the guy the saw and locked him in that room, got the three cards. Put the green one in the PC just opposite where the guy is now locked in. Opened the computer and got a list of programs on it. I click on something and transfer it, but keep getting a error message. I can't seem to be able to take the card back out the pc to try another one?

Am I missing something stupid?
