Pandora Directive: Seriously stuck on day 5

Hello everybody,
I seem to be seriously stuck on day 5. As I understand, I should have been able to enter the Acme warehouse on day 3 - however I didn't do that then. I now need the things from in there to solve the first two boxes. If I talk to Gary, he doesn't give me Malloy's key and just says "no" if I ask him for Malloy, although I gave him whisky back in day 3. Please help me here, I'm really frustrated at the moment. :(
Thank you!

edit: It seems I panicked too early... I only had to show Gary the foto of Malloy... I'm sorry to have opened a thread. Everything is clear now. :)
