I recently bought super meat boy off of the steam summer camp sale and the game will not let me long jump to the right which is required for level 1-3. I can long jump to the left and have tried on different levels but whenever I try to long jump to the right (Shift + D + Space bar) I get no jump, just run. Need help.
Might be just your D key or your keyboard then, if that's the only thing that's different. Try remapping it. (go to C:\Program Files\Steam\SteamApps\common\super meat boy\buttonmap.cfg in Notepad and just change the keys to something else. I use the arrow keys for keyboard, no problems at all)
