Ok so I have used the FTB mod packs for a couple months now and this is a new thing that is really getting to me. When I download the mod packs after deleting the old ones since they didn't work anymore they start up and run fine the first time but then every time after that they don't work. Sometimes they work after I restart my desktop but its most of the time not working and I do not understand why they wont work. Here is the crash log that Minecraft sent me when it crashed http://pastebin.com/p27D1TfF. This is what Forge Mod Loader said, http://pastebin.com/1j71eDyU . Please some one help this has bin going on for about a week.
