Thank you for your replies, I'll post my message in the good section. I didn't know Pastebin, i will use it.

Hi everyone ! My Tekkit UMS was running perfectly since 4 monthes and today, i don't know why, it crashed... No update today, all was fine... Now, when I restart the modpack from the Technic Laucher, it loads the game, and when i click on my world, i see the place where i was when it crashed for the first time, then it freezes and "Shutting down internal server" --> back to Windows. Can you help me to find the problem ? Here is the crash report : *snip* Thank you, friends.
