Problem With Mods Folder

Title: Problem With Mods Folder

Version: 3.1.2

OS: Windows 7 Professional 64 Bit

Java Version: Java 6 Update 38

Description of Problem:

When I try to start my server with all of the files that come with the tekkit server download it will not start it just gives me a long error debug and does nothing else. But when I empty the mods folder the server will start fine and I can join it but not use any of the mods features.

Figured it out. Its a broken mod .jar

Netherores are broken.

[An Hero]

Try deleting Netherores. That tends to be a problem with some servers.
