Bug MOdpack not launching

[R_I_L_E_Y]

MY crash landing modpack isn't launching and it fails to launch but every other pack will launch without trouble I know that crash works because my friend uses the ftb mudpack to launch it and it works but I have to use the mym launcher to make it work but I want to play the single player map and the mym launcher dosnet have map downloads

There are no maps to download, it generates the map automatically

There are no maps to download, it generates the map automatically

but the map only generates on the ftb launcher then not the mym launcher and either way my ftb crash landing dosent launch sooo

I don't know what the mym Launcher is soooooo I would suggest posting on their forums as it appears to be an issue with their launcher not the pack.
