Game SDK

Question

Hi all,
I wanted to ask you a few questions abaot game SDK:
1. Might be really stupid one but ok - How do i know wich SDK am i using , i am asking that beacuse i got it uploaded on my college site and all i had to do is to download it and start working on my project. The main file is named Game SDK and visual studio
files inside it are named 2DGameLanguage.
2. After i downloaded it, i took some tours on youtube to find some tutorials. I've found this guy using the same SDK:
-http://www.youtube.com/watch?v=70eswwFWNHY , so at the time i've decided to start on my own i got stuck wich brings me to next question.
3.How do i load a sprite ?- i mean i have a method  loadSprite wich i've used here but it shows me the error: "Parameter is not valid", been trying to change the properties , saving in other formats (bmp now). As the tutorial on the link above
says "drag the pictures on the project" , i've also done that. Then i decided to post it on one of my forums and i got an answer saying "Don't even attempt to make a game, the logic required is allot higher then what your brain can handle"
, wich is verry encouraging. So i am asking you guys if you can help me, maybe i don't know much abaot SDKs but i am willing to learn.
Thank you.
