Hi,
your description sounds like you are bumping into this bug.
It is fixed in the upcoming Core Update 153, of which a testing version is already available.
Unless some serious bugs or regressions show up, I expect Core Update 153 to be released before Christmas.
Long story short: You could either install Core Update 153 testing (please see here how to do this)
or wait until Core Update 153 is released, which will most probably fix your problem.
I think i will wipe the whole Fire and reinstall it again…
If I understood your problem right, there is no need to do so.
This software is weird…
Agreed, this bug is really nasty, especially to newcomers. I hope you will manage to get it working, anyway.
If not, there is a wiki and this forum available to answer questions. 
Thanks, and best regards,
Peter Müller
