Hello Angeles,
For your second question: Maybe you can compile an older version of Qgis by using Github
https://github.com/qgis/QGIS
How to uninstall Qgis is depending on the way you use to install it before, I guess.
But it would be possible to use different versions of Qgis as well (Keep your actual version
and compile Qgis in a separate folder).
Kind regards
Piet
