STM32 F4 Discovery Demo

I've got a STM32 F4 discovery board for STM32F401with the 9 axis sensors on it. I want to open up the demo project using Keil uVision 4 and modify it. I'm getting an error as soon as I open the project that says Error: Device not found   Device: STM32F4_256KB  Vendor STMicroelectronics  Please update your device selection.

I've enclosed a screen shot of this error.

I don't know what the heck that means. The board shows up in the device manager and is called STMicroelectronics STLink dongle which I think is correct. I've got version of uVision. It is the Lite version.

... actually now that I think about it maybe that's my problem. The Lite version is only good for 32K, right? There is a lot going on in this demo with the accelerometers and such. Is that what this error means? I'm not sure though, when I try starting the debugger I get an error "Cannot Load Flash Device Description" 

Any help would be appreciated.
