My daughter has tried to add a couple of my recent images to her favourite images and they are not registering, or the comments she posted to my gallery either.  She has had no trouble in doing this before, and if she tries again she just receives notification to say that she has already registered.
She is registered as Montspar with Renderosity, and hoping to upload her own photography soon, and of course uses her own computer and not mine. 
So could anyone help us as to how we get over this one please.
