Forum:I gave the chip to Mr.House and now I cant get it back

I did the mission "The house always wins l" and gave the platinum chip to Mr. House, he told me to go back to Fortification Hill. I did but for some reason I didn't get the chip back and now I cant work the machine. Every time I go back to talk to Mr.House now all he says is that I should go back to the Fort as I'll find something interesting.

I don't want to go back to my old save as I have done quite a lot since. Can anyone help?

p.s It's Ps3 version i'm playing
