im using voltz, i havent bothered with custom modpacks atm just messing around on here first! it does tell me that i have a few ids to change and it does tell me which ones but i really dont know how i would change them!!

trying to set up a server and its all well and good until i actually try and go in to it and a message appears saying "forge modloader has found ID mismatches" even though i have downloaded all the updates. dont know what to do, please help
