So, I bought the Sims 2 and it says that in order to install, I need to free up at least 1 MB of space on my local drive. I deleted as much a I possibly could without losing important things. Also, I can't figure out how much space I have left on my hard drive to check. It says I have the device iDisk and so I'll click on it, and need to type in a username and password. I've tried everything to get it, but I don't know how to.
