Trouble with activex object

Hi,

      I have some drawing that have an ole object within. I use insert, object, browse--->then select an autocad file and link it.

Everything works fine until today!

When I want the drawing to open, activex object takes a while to load, and often I got the message " server busy, switch to or retry"

and when it finaly comes to open the drawing, if I double click on the inserted object, it wont open it..just freeze and if I close solidworks, when I reopen it and try to open the drawing again, it tell me: " unable to register the file, the file is probably already open.."

what can be the problem? It works fine with excel bum..So I dont know what to do...

Thanks
