ok so i found the right version and installed it and was able to find it on my laptop but when i tried to connect it said "windows is unable to connect to the ANDROID TETHER network. the network may no longer be in range. refresh the list of available wireless networks and try to connect again. any ideas?
You might try unrooting again using Z4Root. When that is successful try rooting another time, maybe try it twice in a row. Then when you run Wifi Tether, it should load right up. When i9t does, your computer should find it with no problems. Sometimes you have to do some steps over a time or two to get them to work right. Hope that helps!
