Toybox is not working for me, although it is for my friend. HELP!

Toy box worked for me a few months ago, but then it stopped loading a month ago. It just sat there, a grey screen, with google.com at the top; While my friend on the same Wi-Fi sits next to me, Sparta Kicking Daleks and Creepers. I loved Garry’s mod, but it just annoying how many bugs and errors I get. Solution? I want to play garry’s mod again. :suicide:
