Siemens MP377 15" Daylight Readable

Hi,
Has anyone used the new Siemens MP377 15" touch daylight readable HMI?
I am having trouble downloading to it, I am using WinCC Flex 2008 advanced and have the device set as a normal MP377 15" touch, however it pops up a message that says the configured device does not match the target. what am I missing?

This function support only DAYLIGHT models
6AV6644-8AB20-0AA1 MP 377 DAYLIGHT READABLE ( http://support.automation.siemens.com/WW/view/en/37996368 )
6AV6644-0AB01-2AX0 MP 377 not support DAYLIGHT
see manual http://support.automation.siemens.com/WW/view/en/37954241

Thanks, I believe my problem is that I don't have SP1, I am installing that now and will try again.

Ok, I installed WinCC SP1 and still no luck downloading to screen. Can't find any info on Siemens web site as to what settings it needs to have. I have tried Downloading via USB cable and Ethernet cable and it keeps saying device does not match, I can only set it to MP377 15" Touch on WinCC. Any ideas? Thank you
