My modpack doesn't start. Help !!!!

[ModderSucksMe]

So it downloads fine, loads... and then just closes. Doesn't crash, just closes. At first I thought it was still loading but no, it just closes every time. I think the problem is that the modpack.jar isn't the right version, could that be the problem? Check it out for yourself, heres the modpack link- http://www.technicpack.net/modpack/details/acronia.371115    <<<< visit the link. 

 

 

Thanks bros
