i got it to work but how do I make and load a quick save

I installed icepic and then downloaded the files from zweek, then I opened the game through ice pic and when I went to the command section and typed in (Load sfb), then it went on to loading into the level but after a few seconds it took me back to the home page and said that there was an error.

Thanks a lot, I downloaded it but whenever I try to load into one of the game saves it says that there was an error. Did I do something wrong?

Where can I find a mod so that I can practice SFB without having to restart the mission every time I hit a checkpoint?
