Okay, before I tell you what the problem is you must know I am a very experienced rm2k3 user.
Every time I start a new project, all the graphics seem to have vanished replaced by blackness. I can remedy the problem by copying the RTP into the project folder, but how can I fix it to where I don't have to copy the RTP every time i make a new project?
That is incredibly weird one thing I can think of is that the RTP doesn't fit with your rm2k3 but that's silly since you shouldn't be able to open rm2k3 in the first place, did you try reinstalling the thing?
The RTP is the rm2k3 rtp, it works just fine. But I will try re-installing it...
