Planet Minecraft

I get the doku texture and try it out (Before this I removed all mods, since they interfered with Doku) then decided to get mods back. But each time I try to do something in minecraft.jar it says:

Cannot rename [...]\.minecraft\bin\zi04.840 to [...]\.minecraft\bin\minecraft.jar

P.S:

The zio crap changes each time (ex: zi85.b50 or zia78.653)

Never heard of this Solution,
But you named it a .840 file, Which for what i know, Will never exist as a file property, And as i said, i have no idea how to do it, thats just what i can try to see,
Go to your task manager, delete JAVAW.exe
JAVAW again, dont delete java, i meant Close it,
Then try it

I named NOTHING .840.

zi04.840
Was the Name of the thing you tried to rename to minecraft.jar

I didn't do diddly, I left minecraft and tried to delete META-INF since I had force updated to get rid of mods. Each time I try to delete it puts a file called zi04.840 or something similar in "bin" and says the message I mentioned.

Try deleting whole minecraft folder (Backup saves ) And reinstall

What would I lose in the process?

And please specify what to delete when you say "folder".

You would Probably Lose your minecraft.jar And a few server listing, Your saves if you dont back them up,
But your jar dont matter since its fresh,
but just reinstall less you got craplods of servers you play daily

I have one important server...
It's in it's own folder though, and how do I back up my worlds? I got quite a few.
And please specify what folder to delete.

Oh and also I have a cracked minecraft, the only thing it came with is "Minecraft.exe"

Well, put your servers ip in a txt so that you can remember it,
And Move your saves folder or archive it and move it out of their, Pref on desktop, when your done put it back in .minecraft as saves to restore saves

if your on windows:
Go to start
Type in run
Hit ENter
Type in appdata
Open Roaming folder
Find .minecraft
Go inside it,
Move saves folder out to desktop,
delete it,
Force up,
Restore it and add server ip again
Fixed

I shall try

Hey, why don't we meet on the server? I'll post here again when I'm done, then PM you the IP adress.

OH and what about texture packs? Back em up too?

EDIT:
IT DIDN'T WORK SINCE "minecraft.jar" is being used by another program! SCREW YOU MINECRAFT JAR!
