Stuck in "Moment of Silence"

[F.E.A.R. M.E.]

Time for some brain exercise! Although the subtitles had loads of mistakes, and the storyline is a bit dull, I find the game's quests fun.

On with the topic. I am a bit stuck, OK, totally stuck... If you play MoS, and have some time to spare please do help me as the game is new and I am having troubles to find the walkthrough.. And anyways I rarely read the walkthroughs as they contains lots of spoilers.

Downtown:

Taken those "few days off". Talked to Greenberg about everything and with Brian too, I think. Bill's in the kitchen, the upload's terminal is free, but what is it good for me if I don't have the disks? Talked to Claire long enough to get upstairs, no more.

Lower Eastside:

I've already got my messenger stolen and got it back. Lou doesn't let me through the back door, though. All I've seen useful in there, was a 3GHz computer Gained Rita's business card. Or whatever that card's called.

P.S.: When I talked to Bob in Brooklyn after this little adventure in Lower Eastside, there has opened a new dialog branch "I've found the Alien Attack Club". Is Nuclear Cafe the Alien Attack Club?

Brooklyn:

Talked to the Guru, to the groovy 'n' deaf Guitar Player. There was a casket and the sleeping place, but as I understood it doesn't give much anything. Bob's been "interrogated" thoroughly. The game doesn't let me into the Oswalds' appartment, Tommy's in school, and Peter says he must let them rest. Talked with D. Oswald about everything on the messenger. She mentioned Queens, but unfortunately no Queens appeared on the map in SatCars.

Items:

Rita's card, alien figure, messenger, business card, Graham's picture. I think that is all.

If you are too busy, just drop the link to the walkthrough...

Thanks.
