FTB Unleashed world not loading

[Artician]

Hello,
I have been playing a world on singleplayer using FTB unleashed for the better part of the last couple months,and have built a lot of stuff. Today my world stopped loading, and I am unsure of why. I sent my log to pastebin, and it can be viewed here: http://pastebin.com/LwYfgLEj . I have tried deleting forcedchunks.dat, and cannot see any of the other files that people talk about. I really do not want to remake my world. The only thing that I have done since closing my world last night was to update ftb launcher. If anyone can help me, I would really appreciate it.

Bumping for help. First and last time.

Your log has been deleted from pastebin.com, but from what you describe it is more than likely your over zealous antivirus program. Try adding the mod pack folder to the exclusions list of your antivirus program. Be sure to check any box that says 'include sub-folders' so it applies to all the packs.
