Holy crap it worked! Thanks man! I suck with computers, and whenever I download something and it works I feel good inside! 

take the .smbl files out of the Hellostone folder and put them into the levels folder and then it should work.

how do I do that?

im getting the levels from: C:\Program Files\Steam\New Folder\steamapps\common\super meat boy\levels\Hellostone

Do i have to "extract all" from hellostone 1.0?

Hi. 

I wanted to play "hellostone national park" (a custom chapter), so I downloaded it into a folder I made called "levels" (in my meatboy folder). Devmode works fine, but whenever I type in the exact name of the level it does not seem to work. Help please!
