My son and I made our first bit of progress last night by getting our little bot up and going. But when we opened builder this morning, we noticed the "update available" tab flashing so we clicked on it. it took us to the download page which we did and everything went normally until we clicked on "finish" to exit the installer. The little hour glass icon appeared and didn't leave- for hours. finally, I restarted my computer, only to find that builder wouldn't open. Nothing unusual happens except it won't open, actually nothing at all happens.
