Choose the table you want and download the rom (leave zipped) to the ROMs folder in your Pinball directory. Then, you must also download the table and extract it to the Tables folder in your Pinball directory.

Run Visual Pinball and go File>Open and select the table. Click the "play" icon and you should be off to the races.

I got the emulator loaded but when I try to load a rom it says:
ROM set is missing: VPinMAME can't run the game.

I click on continue anyway and it will show me another message: machine terminated before initialized, check the rom path or rom file!
I click OK and the table loads.
I insert some coins and hit 1, not on the num pad though, and the game won't start. I hear the coins drop, and space bar will nudge the machine, but the game just won't start.
Help!

So check the ROM path.

Sounds like VpinMame is looking for the Roms in the wrong folder. Tell it where to look by adjusting the paths within the VisualPinMame setup within the Pinball folder.

it looks like they are pointing to the right folders. Would screenshots help at all?
