Title: Tekkit Isn't Starting Version: 1_0_3 OS: Windows 8 Java Version: 1.7.0_45 Description of Problem: In an attempt to play Tekkit after having not played it for months, I attempted to run the mod, and now when I start it, I get this message. http://s1165.photobucket.com/user/_Archimedes_/media/TechnicBeingStupid_zps690b8f5d.jpg.html I looked through the folders, and eventually found CoreMods. After deleting what I assumed what was minecraft version 1.5.2, I attempted to start the program again, and it repeated the process. Can anyone help me? Error Messages: Error Log:
