Reinstall Fresh CMS

[ProFifaLeagues]

Hello guys and thank you for any help you can offer me.
Ok with the forums and Cms blogs all installed I would like to Replace the changes made on the CMS and start again but leave all my forums and blogs in place with no changes to them.

Is there an easy way to Do this on 4.2 please?

Did you try uninstalling the cms and then running the upgrade script again?
