Character improperly sized

[Duck]

Basically, my problem is that my character is way too small in the game - yes, smaller than his sprites. The sprites are about 40 pixels tall; in the game, the character is no more than 15 tall. It's a 320x200 game, and when I click on the sprite in the sprite manager, it says that it was made for 640x400. I tried re-importing all the sprites with the "import for 640x400" button checked, but it didn't work. I'd really rather keep my game 320x200. A bit of help?

uncheck the import for 640 * 400 and it should import for 320 * 200
