Problems of drilling on OrCAD.

Hello, I subjected a PCB on www.batchPCB.com with the following files: TOP, BOT, SSB, SST, SMB, SMT et truhole.tap, but I have a problem :

Warning: No drill points were found, if you do not use drill holes please ignore this message. Otherwise please check that the drill definitions and drill co-ordinates are in the single drill file, please see the FAQ for more information.

I don’t understand why, can you help me ?
