Needs to download rapidweaver 4 2 on my new pc

I just bought a Windows 8 pc and I am wondering if Rapidweaver is compatible with it. I previously used my MAC for this Rapidweaver 4.2 and I am wondering if I can transfer all my files and the things that I have already created on my MAC to my Windows 8 pc. I am not really sure if they are. Do I just download rapidweaver to my Win 8 and start over? Or is there anyway I can transfer everything and resume what I did on my MAC to my Win PC.
