My own custom modpack wont launch. (please help)

[Kamina]

I created a custom modpack just so my friends and I could play.

When I click the "Play" button for my pack, it downloads everything, but never launches.

Here is the log files I have:

look a bit closer.

it is not downloading your pack.

[Kamina]

It has all the files

I checked

[Kamina]

It has all of the files and it has been downloaded. I can find it with the other packs.
