technic launcher Failed to run mod

[CryoftheWolf]

Hello, i have the Technic Launcher and i can open it, but when i try to play/run a mod pack it runs the loading bar and then the Technic Launcher flashed once after it loads but it wont open the mod pack. I have tried...

* uninstalling the launcher and reinstalling 

* removing the mod pack and then installing it again

*i have Java 8

*my computer should be able to run the mod/mods fine(the pack was working before i rebuilt my laptop).

If any of you guys/girls know how to fix this problem, could you please give me a hand?

Thanks. <3
