I've downloaded a source and client bundle from the "HQ RSPS Downloads" section of the website, and it's this one to be exact. There were a few errors I was able to work through and figure out on my own, but now I'm getting this error, and I can't seem to figure out what to do from here, as I'm still relatively new to this. As I've said in the title, any help would be greatly appreciated ?

Right click -> run as -> java application -> add -local to runtime arguments.
