Sorry Karen, The software isn't broken as technically the software isn't even delivered yet. If they release 1.0 and then its broken...well the time limit for a return will have passed so...
Although it sounds like you are not a good candidate for Early Access games. Although at this point there isn't much that can be done. Maybe for future when you see Early Access tags on things that you just give it a pass so you don't burden people with your problems.
I imagine you are not getting much sympathy from any of the forums. Reading is fundamental.
