I don't know much about Java or anything like that so i didn't even bother reading through much of that, if anyone could help me that would be great!

 

BTW:

 

I installed this on a fresh minecraft.jar 1.3.2, nothing added on, directly downloaded from the website, and this error occurs during the FML installation process, I'm running this for client aswell.

Verify that the files listed in the log as being downloaded are in the minecraft/lib folder.

If they are not, download them an put them there.

Thanks for the help, it's working perfectly now
