I have tried a few times but the download is in giberish just a bunch of funky numbers and letters
We've run into that a few times. Seems to be a mystery setting in Internet explorer.
Do you have another browser you could try? Chrome, Firefox, etc? Those two save the download in a file marked 'downloads' and opens them right up.
If you only have IE, is it giving you the option to open or save? If so, try saving, then check the extension. For some reason a few IE units try to save as '.html' instead of '.pdf'. You will get gibberish this way also. Just change the extension back to .PDF and away you go.
