Import .brd (allegro) to Altium

[forever3000]

I have 1 file .brd (pcb in allegro), my laptop was installed Allegro 16.6 and Altium 10, I tried to import this one .brd to Altium by import function on Altium,
got successfully and I had a .pcbdoc in Altium but still have some problems.
Have many nets still haven't been routed, many pads not correctly ...
With this .brd, I open with Allegro 16.6 got nothing wrong.

Anyone can help me?
Thanks .
