Snap as modem via USB

[gtsps]

OK so I've been looking on here for an hour or better trying to figure out how to get this friggin Snap to work as a modem. I keep seeing people say to download this and download that and go to the registry bla bla bla. I'm not a I computer wizard and I just want this flippin thing to work. I've downloaded a few different programs now and some will isntall and some wont. Every time I try to connect to internet sharing it comes up with code 67 I believe it is and says something about a sprint user name and password. I don't recall ever getting a sprint username and password so I have no idea what they are talking about. I don't know how to get into the registry to change anything thoug I've downloaded a program that is supposed to allow me to but when I try to open the program it says I need to open the app then open the program while in the app. I have no idea what this means.

So can someone please explain to me in detail step by step in laymens terms how to make this phone tether with my computer for internet sharing via a USB cable?

If it matters the plan I have is Sprint's Simply Everything plan.

Thanks so much for any help!
