EndNote web transfer looping

hi, I have just upgraded to X4 from X3 (on a mac).  I can see EndNote web, inside EndNote.  I have configured it with my user name and password so “transfer” appears.  However, when I try to click on transfer, it seems to jump / take me to “all references”.  I previously had no problems using transfer to / from EndNote web with x3.  Can anyone please give me some help? Thank you!
