Black Screen Help

So, I'm using Fsod source and when I tried to implement the "mscale" command the screen goes black. There weren't any errors that occurred when I was copy and pasting the stuff/when i saved it (the swf). Any ideas on why this is occurring.


(P.S)
I'm new to the private server thing and might have left out some crucial info.

Probably just some errors copying and pasting, and no other info given aswell. Does it load the cursor atleast, or is it compleetely blank? Are you using Intellij or FFDec.

It comes up with a black screen w/o the cursor. And I'm currently using FFDec.
