Did it crash as it loaded? Was this the first time running the pack? Which pack is it? Have you made any changes to the pack (other than adding optifine)? Can you send the following file "C:\Users\Frostbite528\Desktop\Ultimate\minecraft\crash-reports\crash-2013-04-16_17.31.54-client.txt" to PasteBin and post a link and do the same for the Console log? And finally how much RAM does your PC have?

Seriously we need all this info before we can help looking at the problem, so far all we have is a partial crash report, sorry.

It's an id conflict, between the portal gun and logistics pipe sign.

Ok that might be an older crash report then... Which version of MFR have you updated to?
