PW integration with OpenBuildings Designer

Hi,

I installed the latest edition of OBD Update 5 but cannot make it working with PW Explorer 10.00.03.49. I know it's not the most up to date version of PW but my IT department is reluctant to update it. Is it possible to make these two working together?

I've also got the latest Microstation Connect Edition Update 13 and it works fine with PW.
