can't select on defpoints layer 1

[javak]

i've used plines to form boundaries in which i have associative hatch, i've put the boundaries on the defpoints layer, although i've moved and modified the plines many times before, today i can't move them , or erase them, or even select them

can anyone tell me what i need to do in order to select objects on this layer again?

thanks
