Voltz server help!

[Cliffy36]

Hey guys, i am trying to start a voltz server. but everytime i click the launch.bat file it launches but then i get an error message that says:

Exception in thread "main" java.lang.runtime

Exception: java.lang.noclassdeffounderror: com/google/common/colect/multimap

at cpw.mods.fml.relauncher.FMLRelauncher.setupHome(fmlrelauncher.java:175)

it repeats the last line (cpw.mods....) with different numbers at the end. And at the end of the cmd prompt it says .... 11 more. If anyone has any ideas please let me know. I am running windows vista. Thank you all!
