Please help me with my server for 1.7.2! [MAC]

Okay, I was trying to "port foward" my server with uTorrent (let me know if thats an acceptable program to use) and it wasn't working so I deleted the program and then tried to boot up my server and every single time it would crash!!! I hope somebody can tell me what this means and how I can fix this (if possible)
Here is the crash message:

Loading libraries, please wait...

PLEASE HELP. I have a lot of stuff on there that I DO NOT want to lose! I've spent hours on it! :(

I don't think you're using the right CB version. Try getting the latest 1.7.2 version of CB

I'd advise you not to set an IP address of your server in the file.
If the local IP address changes this can stop the server working.

the server may be trying to connect to a certain IP address, try changing the Ip in the server.propereties file to localhost or your internal IP address
