This means PCB does know about your netlist, but you have a lot of short 
circuits. This is common when you first open the board after a gsch2pcb 
step: all components are placed at the same position, many pins sorted.

Try to move them around until there are no touching pins or use "disperse 
all elements" (in the "select" menu). When done, press 'o' (optimize 
rats).

If that's not the problem, we may need to see your footprints as well 
(there may be some overlapping pins in there).

HTH,

Tibor
