In install folder for Chapter 1 Episode 2 you have a text file "Read Me!.txt".
The text file says this:
1. Install "UDKInstall-EP2v1.4.exe"
2. Replace folder "User Code" in ...\Binaries\Win32
Meaning you should:
1. Delete the "UserCode" folder from "Ch1Ep2GameInstalledDir\Binaries\Win32\"
2. Copy the "UserCode" folder from game installation folder
3. Paste the copied "UserCode" folder into "Ch1Ep2GameInstalledDir\Binaries\Win32\"
