Adsense - complete reinstall required if already running latest vB version?

[stained]

My apologies if this has been asked before but I've been unable to find anything on a search.

My VB installation (currently 4.0.2 PL1) was previously associated with an Adsense publisher ID which was never fully activated. I don't know why but it wasn't and I never received an email from Google with activation instructions (I waited for months). Anyway, I've just created a new Adsense account which is now fully activated and associated with my VB account but of course the old publisher ID is still showing in my admin cp. I have followed the instructions in the VB member area and have downloaded a new 4.0.2 PL1 installation which is now associated with my new publisher ID. However, I already have 4.0.2 PL1 loaded and running so my question is: must I upload ALL files? I'd rather not go through the hassle of fixing my style/changing templates to allow my hacks/mods to run so it would be great if it were possible to upload only those files necessary to get Adsense running. I understand that this was possible in 3.8.x. Is the same thing possible with VB4 suite?
