Door text gone and vending machine

I have just started working on my 2.5 server and i added a new hud after that i get this error and you can not see the text on doors and my vending machine addon.
Also my f4 is black and purple how do i fix that.

It says not to change the darkrp in the new 2.5 so im not and was wondering if there is anyway to fix this with out doing so.

Can try help you, add my steam?
