iChat Issue (GreenLight but no Invite)

Hello All!,

Quick question,

I been having this issue lately (since the update to yosemite) that when i get ichat invitations to video chat my light turns green but no actual invite comes up on my screen. It is becoming very annoying to use facetime and I am wondering does anyone know how to possibly fix this?

I tried everything but it still does not work.. ANyone know anything?
