starmade update issues

[Pertominus]

we are unable to update our starmade server. the updates appear in the update tab but i am unable to download or install any of them. when i start the task of doing so it gets to 10% progress and displays 'copying directory' followed by 'error 505 the system cannot find the specified file'

 

The server is now several versions behind and traffic is non-existant. the server and all money put toward it is being wasted.

 

if anyone can help, pls tell me what im doing wrong
