I'm stuck on the underground lab of act 2 level 1. I talked to the red head but can't find the key cards for the rooms especially the secret room. I have the v1.01 version. Can you give me a hint where to find them. How do you get in the room that says "You see a 'A' letter on the lock."?

The room that says "You see a 'A' letter on the lock" means that you need a key for that room. Be sure to check your keys you collected.
When you talked to the read head you should by now be heading to the underground lab. In there you need to collect keys/ cards that open specific doors. You might have missed them.
