BB 3.5.03 -> 3.6.04

[sonnyh]

Hi,
Here I am again.
Apache 2.4.52
Php 7.4.28
SMF Version from: SMF 2.0.19

I am trying to update BotBanish from 3.5.02 to 3.6.04.

I have tried to uninstall 3.5.02, and broke SMF, so I  restored SMF.
There are several .htaccess files and several 2019-06-16_backup_BotBanish_Client_SMF_v3.tar.gz
and several 2019-06-16_before_BotBanish_Client_SMF_v3_X.tar.gz.

Looks like duplicates with different dates.

Not really sure where to start, and what files need to be saved and what files can be removed.
