Which Fox-it reader free download is the authentic one and can someone who has it give me the right site?

had adobe but it won't work any longer and has been that way for some time now. I was told to get the free fox-it reader and it worked great but my internet was off for a while and when I tried to view a PDF file it wouldn't open so I tried to fix the adobe reader 9 without success and then deleted the old fox-it reader and I was gonna install the newer version but when I looked there are several different ones so I just want some advice on which one from someone who has it. Thanks.
