I didn't see this thread when it was first posted for some reason. Missing graphics, if you have them as files in your machine, are usually fixed by copying them into the Mach3 folder called bitmaps. The usual install also expects the location of Mach3 to be C:\Mach3 so the files should be copied to C:\Mach3\Bitmaps if this is the case. It is the first place the screen set looks for them if they are not where the screen set expects them to be. I have never installed Mach3 anywhere else so do not know what will happen if it is in a sub-folder or on a different drive. The license details at the top of the screen look like a China Cracked license so you will not get any official assistance from the official Mach3 sources.
The screen shot looks like the downloadable 6 Axis Screen available from Newfangled Solutions so if you cannot find the bitmaps on your machine it is probably worth downloading this and copying the bitmaps from it into your controller.
