Some mod packs not working.

[StigZG]

I have a problem with some mod packs, I can't play with them. When I tried to download the FTB Retro SSP pack, I got this message in the console: "Eception in thread "Minecraft main thread"
java.lang.RuntimeException: sidedDelegate null when
attempting to getMinecraftLogger, this is generally
caused by you not installing FML properly, or installing
some other mods that edits Minecraft.class on top of FML
such as ModLoader, do not do this. Reinstall FML properly
and try again."


When I tried to download the FTB Unleashed pack, the console said: "JavaVM FATAL:lookup of
function JAWT_GetAWT failed.Exit"

If you can, please help.
Thank you.

A couple things you can try if you have not already. Follow the basic troubleshooting guide carefully and fully. This guide fixes a lot of errors. Take special note of part 4a if you are on a Mac. If after following the guide you still cannot get the packs running or get any other error please post the whole log to pastebin.com by clicking on the 'Paste my log to pastebin.com' button. This will add a link to the bottom of the log that you provide to us so we can see your log.
