Hi guys, I bought lightning returns from steam today. To save time, I have gotten the installation files from alternative way. now my question is, how to make steam verify integrity of the game cache? I notice that the download folder for LR is here: steamapps\downloading\345350 I copy pasted the game files to the folder, and verify the game integrity and... nada, nothing happens. I really don't want to download another 15 GB files if I already have them. can someone help me?
