Rockmelt no chrome apps?

I installed Rockmelt. but everytime i try to get a chrome app, it says that my browser isnt supported and tells me to download Google chrome. How do i fix this? the same thing happens with extentions and themes. Also is there any way to make it one bar at the top not many? finally can i list my facebook friends first online then favorite?|||try again now. i had the same problem, and now it's letting me install apps and themes and all that other jazz. :)
