Sounds like two pins are assigned to the same location, which would be an error on it's own.

I used the ALTLVDS for the serdes then i had 4 outputs, and to have the (-) and the (+) for each one I used ALTIOBUF. When I assigned the pins name in the assignement editor I don't know which caracteristic I must have to this pins. hope I was clear and thank you a lot for your replay.

As discussed in many similar threads, you don't need an ALTIOBUF primitive to assign LVDS in- or outputs. Just assign an LVDS IO standard to the non-inverted pin of a differential pair. Quartus will supplement the inverted pin assignment automatically.
Stratix family FPGA have dedicated LVDS in- and output drivers. You can only assign one of the dedicated drivers. The Quartus Pin Planner can ease this operation, because it knows about available pin locations.
