everything you download from this site is a ziped file. BUT its not just zipped, its highly compressed into a ".rar" file type. windows software will not be able to open it. you need a program capable of uncompressing this info. (yes windows has a zip option, but its not made for compression, only grouping files) I use a free trial program of winzip a trip to google town for winzip free trial and you will have it.
once you download the files from viking, if using winzip, you must extract the documents inside. once extracted, you can trash the zipped file, and use the extracted files.
your x button is not working because your controller needs to be programed for the first time. it is normal.
after extraction of the files as discribed above, click the option in the hidbootloader to "allow word configuration" and program the halo file into the controller. this will clear up all your problems
