Hi,
this post belongs on the Mah4 General Discussion board, no doubt Tweakie will shift it there.
Just download and install the later build, and it essentially overwrite what is already there, you don't need to do anything.
If there is a profile and/or a screen set that you wish to retain then they must have a unique name.
For instance if you have used wx4.set as your screenset, and have over a period of months added various tweaks and edits then when you up-date the wx4.set will
be overwritten by the new incoming wx4.set, and all your edits and tweaks will be lost. If however you name your screenset Mywx4.set for example them it will
not be overwritten on up-date.
The simplest explanation is that if you want something to survive an update unaltered then it must have a unique name, be it a profile or a screenset.
