Try downloading multimc from forkk.net and import it using the button in the dropdown menu. Then try launching it through multimc.

i got it to work on multiMC, thx guys for your help

You also will likely get it to work with the launcher by completing the following:
http://desk.feed-the-beast.com/index.php?/Knowledgebase/Article/View/9/0/basic-troubleshooting

1. Your Java is out of date, and newer mods that require up to date Java (7u25) will crash your modpack.
2. Line 66 reads:
  1. Added URL to classpath: file:/D:/Users/Wang/Desktop/mystuff/minecraft%20tekkit/FEED%20THE%20BEAST!!!/Ultimate/instMods/liteloader.zip
You can't have tekkit in the name of the filepath. At least one mod in the packs will not launch with Tekkit in the file path
Also, there are spaces and special characters in the file path, which will hinder loading/updating in some cases.
