i am in need of some advice when it comes to installing mo creatures mod into the direwolfpack on the feed the beast mod pack. when i bring up the launcher i did install the mods through it, but i get black screened when i load it up. if anyone could help me out it would be much appriecated! thank you!

pretty sure yes. this is the big issue i feel. when i chose these mods to install into the feed the beast launcher it black screens, but when i disable these mods the launcher runs fine

When you launch FTB, theres another window that launches with the game. Its an error log. Make sure all the mods you want are installed, and then copy that log file. There should be a button that lets you do that. Upload them to pastebin, and either put the error on the FTB support site (http://desk.feed-the-beast.com/) or on here. I can do my best, but It could be any number of things. If you do post it here make sure to put them between spoiler tags.
