Any custom I add is a black box...

[Lasers]

I've coded my own customs, got customs from rz/db, and even took customs then just changed the pictures of them and they all still show up as black boxes. I ran the SQL, put the SWF into my swf folder, put the furnidata info into furnidata.txt, restarted my EMU, deleted my cache, logged in and out, restarted xampp, I even deleted my cookies and yet they still appear as black boxes... I'm Currently using RevCMS with Gold Tree EMU. Please help, this is very, very frustrating.
