Hey everyone, I'm new to Minecraft fourms... I don't even know if I'm posting this in the right section. But as I mentioned in the title, somehow I can't use my 1.5.2 worlds for 1.6.2, when I got the new 1.6 launcher. I created a world in 1.6.2, then I checked inside of the saves folder in my .minecraft, and the new world's folder wasn't there, only the ones I had for 1.5.2. I searched up my problem on google, and got no results, so i'm assuming probably no one else is experiencing my problem. Am I doing something plainly obvious wrong? Did I get the wrong launcher? Are my files damaged or something? Help please~
Thanks.
