Thank you to the readers that sent in information regarding this problem. Names from the emails and the Black Library response have obviously been removed.
I noticed that the digital version of WD55 from BlackLibrary was missing "The Rules" section after "Paint Spatter" that would have the rules for the Starweaver and Voidweaver.
I e-mailed BL customer service and they replied this morning:
Here is a response from the Black Library regarding the problem
Thanks for your email. It appears that Cegorach wanted to keep a few secrets to himself. We have now prised these from his grasp and you should now be able to re-download your copy of white dwarf and gain access to the Starweaver and Voidweaver rules.
