Two errors

Sounds to be related with the ad module.

I have also received two errors:

* Warning: Parameter 1 to ad_external_node_view() expected to be a reference, value given in module_invoke_all() (line 819 of D:\wamp\www\xxxxx\includes\module.inc).
* Warning: Parameter 1 to ad_external_node_view() expected to be a reference, value given in module_invoke_all() (line 819 of D:\wamp\www\xxxxx\includes\module.inc).

how i solve this error???
Thanks
