Well if you have access to FTP (File transfer protocol). Log into that. If you don't know how to, use filezilla. Google it.
Once logged in. Don't do anything yet, instead put this file into an empty folder on your desktop. And click the .jar file. It will load all the folders.
Now finally, rename the .jar provided with the MCPC+ mod, to the current .jar you run. So default would be minecraft_server.jar. I run it on custom.jar.
Once this is all done, try and replace everything loaded in that folder with the stuff on your server. So delete all your lib files and replace them with these.
The mods and coremods folder don't need to be changed on the server. Unless there is something generated in any other files you shouldnt need to replace them eather. Then simply.
Start your server!
p.s. Funny thing most people don't know, if you want to try a server that runs this. I have it in the custom server section. Oh and im 14. Thought i might share that. Partly why my spelling may be bad. Just like to thank everyone here for the support as most the bugs in my modpack ive managed to sort out through you guys. I hoped this helped everyone with querys.
This is the way i had to install it. My server host uses multicraft as a server manager, which puts the .jar file into a separate folder. So without this i wouldn't have realised it needed to generate all those other files/folders and they'd be in the wrong spot. So thanks.
I really can't believe you're just 14, makes me feel dumb as hell. Nice going man!
