How can i free space i dont have room to download anything

click on my computer, right click on your C drive, go to properties -> Tools -> Disk cleanup. that will help some but it is your responsibility to manage the files on your hard disk. You will want to delete any files or folders that you dont need anymore. for example check your My Documents folder, Downloads folder, Music and Video folders. Do you really need to hang on to the entire series of Battlestar Galactica anymore?
