No it will not
delete a mod maybe and force the update?
The only way to delete mods easily (when not using a mod installer) is to force Minecraft to update before you log in to Minecraft go to Options and Click Force Update, then log in Minecraft will re-update itself to the current version
You dont.
You might have to update your minecraft
you go on minecraft launcher and go to options and force update you cant update if you got classic
Coppy your world somewhere safe and keep the ip. Then delete everything. Download the latest Minecraft_Server and place it where you want, run it, then delete the world and repleace it with your old one. Next open the Server text folder and put in your ip.
You can, it should be in a update soon
Either the server needs to update or you need to update.
You update your minecraft or get the older version. If your minecraft version doesn't match the server's version, then you can't join it no matter what you do.
It usually means the server version is older then your game version. Every time Minecraft updates they usually update the server also.
if you are using windows 7 1 click start, type %appdata% 2 open . minecraft and delete bin 3 start minecraft and update if you are not using windows 7 1 click run/%appdata% 2 open . minecraft and delete bin 3 start minecraft and update
Nothing you should know its past that update so that will never be answered
