Can't download my own modpack "error unpacking zip file"

[Kazu]

Hey Guys.

I've just finished setting up my modpack and everything the tutorial said but it won't download the modpack properly.

That's how my zip archive looks like:

modpack.zip

- bin

-- modpack.jar

- configs

- coremods (I know there are no coremods anymore)

- mods

The modpack.jar contains forge.

My modpack is based on 1.6.4 but as soon as I try to download it crashs.

The .zip gets downloaded and the launcher is trying to extract it but as soon as it gets an empty folder it crash with the following message:

"error unpacking zip file".

I don't know what to do.

Why do you need empty folders? Minecraft will reconstruct folders it needs. Delete the empty folders. If that doesnt work, post your zip and I can take a look at it for you.
