I have MCLauncher (By Digi)

But, i cant find the minecraft.jar that goes with the sever. can you tell me witch one it is?

 

I think you can switch which jar you want to use through the client startup

 

Doesn't look like 1.4.5 is available yet to download from that launcher. Googling "minecraft 1.4.5 jar" does the trick though

Bukkit 1.4.6 is out now, i believe

 

-_- Nobody is getting the hint. You need a lot of the plugins to be compatible. Just please be patient. Max is a busy person and he'll know when it is time to switch to 1.4.6
