Airport Express Airplay no longer compatible with iTunes 11.3

Hi,

Everything was working perfectly until this morning when I updated to itunes 11.3 (54) 64 -bit, now I open my itunes and try to select my airplay speakers connected to an Airport Express and the message appears "The Airplay device is not longer compatible with this version of iTunes" I have a Mac Book Pro with OS X 10.9.4 installed.

Any help will be much appreciated.
