To establish a baseline, please read the quote. Many problems are solved by the troubelshooting guide, and those that aren't, we can work on from here.

Please read below. Please be sure to read all of the info available in the 2 articles.

Spoiler

Please follow these steps exactly: http://desk.feed-the-beast.com/index.php?/Knowledgebase/Article/View/9/0/basic-troubleshooting
This is to rule out any issues with your setup. Please also read the extra info at the bottom of the guide, and apply all applicable suggestions.
Please attempt to launch the modpack, and open a new world save to make sure the setup is correct.
Now, continue on to check your previous saves, changes to the pack, textures, etc. until you're able to reproduce the error with the clean setup.

When the error has been repeated, please post your complete client-side (launcher) console log in debug-mode to pastebin.com and link your paste URL here.
To find your logs and prevent them from expiring: http://desk.feed-the-beast.com/inde...29/1/what-log-do-you-need-where-can-i-find-it

You can also try renaming the save folder.
