Solved! Forgot to download XNA Framework 4.0 on my computer sorry for all the trouble!

My client isn't the problem the client works fine with forge it's just my minecraft server any thoughts?

Ok I tried this,still got the same error. Any other solutions? (Reason I said I didn't understand was because I tried it and it still didn't worked so I assumed I did it wrong.) *Edit, Can it have something to do with me also launching a regular server without mods and still getting a error (Different type though with a clean server I get tons of Java errors. To be specific Null errors and initialization errors)

Wait a second, Im sorry to ask but can you tell me that in a different form? I don't really understand what you mean by that.

My friend sent me those files the server worked perfectly for him.Any solutions? *Edit Sorry for being kinda rude, lol.

Whenever I start the server I get an issue.It wont actually start up! Please help me I dont know whats wrong. I download the lib files from the log how it says so but it still gives me the error (It wont let me download the deobfuscation file though it says unknown file or something like that when I go to the link so I get the deobfuscation file from my sp .minecraft lib but it still gives error) Here is what the error looks like. http://pastebin.com/yHDFfsYd
