It is not a waste of time to find all the ways that don't work... each one is a step closer to the way that does work and may help someone with a similar issue. Please don't think you wasted our time. We volunteer our time freely because we believe in this OS and we enjoy helping others. You are welcome to ask for help any time, whether we are able to is another matter, but we'll try. Maybe in the future you to will find the joy of helping someone solve an issue... maybe not (it's not everyone's thing). Either way its what we enjoy doing.
Please let us know if 16 works for you or if you have issue with that as well, though some of these tips may solve any issue that arises.
Thanks for being a part of our community.
