WINCC FLEXIBLE COPY PROJECTS

hi everybody, somebody can help me?
Im doing a project with simatic cpu-315 with ethernet onboard, and wincc flexible 2007, im going to use a pc for runtime, with my bad luck, i only had plcsim 5.3, and the ethernet connection doesn works, and i made all the graphics and images with a copy of my step7 project and use mpi connection and integrated to the project . now i have plcsim 5.4 for testing with ethernet connection, the problem is how copy the old project in wincc flexible to my project with PC Station, and IE-General for ethernet communication i do this beacuse you have a info about how to connect s7-300 with ethernet connection to a pc runtime, and its necesary use a pc station and made some changes .
but now the only way to copy the project is open 2 windows wincc flexible and copy one to another
But there is somesimple way?
And do you know what other things i have to check for made the 315-pn/dp to a pc runtime comunication????
Thanks
