Recordnow and pioneer 109


I have to re-install all my computer, and now (all worked perfectly before) Recordnow DX 4.61 did not even show my pioneer 109 writer in the left menu.
I try to desinstall and install recordnow again, and nothing ! I put pxengine 507 with all speed dll, and nothing, no dvd writer, only my dvd reader and my cd writer appear.

Could someone help me ?

Thanks in advance
