I use Windows 8, but I don't think your operating system would prevent you from using it. At the bottom left corner of the SpoilerAL title select menu there should be a button that says location of the SSG file. Press that and select Kei file from the menu that pops up. You should be good after that.

Getting new characters involves overwriting the data for characaters you already have. That's not a problem in normal gameplay, where you can just capture some generic unit and then turn it into Kamui, but in Chaos Mode, where you only get to play with the characters you've cleared (no jail), it's not really worth it. Beyond that, there's a hard limit to the total number of units you can have (I think it's 89... maybe?), so once the number of characters you have goes over that the game actually forcefully takes some of them out of your party (Gou says they "accidentally" got injured...), so I only ever hack new characters in on Normal or Hard mode, since there's pretty much no way of recruiting all 71 of the "real" characters in one playthrough.

For now, just enjoy Chaos Mode. Or don't, since it's close to impossible. That said, I still reccommend beating it, since its story is pretty incredible, and the revelation of who the true mastermind behind everything is is amazing.
