I've just tried to update my server to the DW20 1.6.4 pack and when I tried to relaunch the server it said it couldn't access ForgeMod.jar. Anyone have any idea.

Here's the log:

I do apologize if this is just me making a silly mistake, when updating in the past it has just been a simple as uploading the files to the server and restarting, never had any real problems before, thanks to anyone who helps!!!!
 
This MCMyAdmin log doesn't really show the reason why the server is not starting. If you look at your server.log or ForgeModLoader-server-0.log these will show more useful information.

Have you tried starting the server without MCMyAdmin? It certainly isn't my recommended server wrapper, but that's just my 2 cents.
