Insync won't start after instalation

Hi!
I’m trying to install Insync-3.1.7.40811 on a MacBook Pro running MACOS X Yosemite. I copy the app to Applications folder and run it. The program starts and I get the Insync Icon but only a blank window appears that does not allow any interaction.
Any help? Maybe the OS X version (I can’t install a newer one because it’s a mid 2009 computer).
Thanks
