I've been playing Batman: Arkham City without any issues on PC (I bought the game from Amazon, not Steam) but I've run into a major glitch that isn't letting me finish the game.

After being saved by Catwoman, I scanned the helicopters until I found the one containing the Master Control Program. Once I found the correct one, I witnessed Batman removing the MCP and telling Oracle he had the MCP. Unfortunately, when I try to get through the TYGER security gate, it says that I'm missing the MCP.

I see other people are having this same error. If a patch as been released, can someone please direct me to it so that I may download it?

I am using Windows 7 (64-bit).
