Simply unzip the sabbyserver.zip wherever you like. There is no need to install the sabbybot_sig.cer in your trusted root simply leave it where it is in when you unzip the file. However, you should only used the sabbybot_sig.cer downloaded from the SabbyBot site otherwise a third party could potentially distribute an unauthorized version. If you have any doubt about the distribution you have obtained simply download the sabbybot_sig.cer from the SabbyBot site and overwrite the old file with the one you have downloaded. This will ensure that the version you have is from me or an authorized distribution point and has not been modified. After you have unzipped the archive start the server, fill in all the setup options, choose your skin, and restart after that you are good to go. You can use your custom commands (command.obj) and ban nick names (nickname.obj) from the old SabbyBot to the new server if you want, simply copy them in the executable directory.
