Failed compiling 'SignArtist.cs':

1. There is no argument given that corresponds to the required parameter 'entityID' of 'FileStorage.Remove(uint, FileStorage.Type, NetworkableId)' [CS7036]

(SignArtist 40 line 529)

2. Argument 1: cannot convert from 'NetworkableId' to 'byte[]' [CS1503]

(SignArtist 59 line 532)

I'm getting this error:
