Create ffdshow audio processor instance error

Question

I downloaded latest ffdshow (ffdshow_rev4527_20131203_clsid) and installed it. I want to use ffdshow Audio Processor filter in my application. Whenever I want to create an instance of it, fails with cast error. Neither GraphStudio nor GraphEditPlus can add filter but surprisingly GraphEdit can add & use it!

Do you have any idea? I set "no limitations" for number of instances.

Thanks

It was my fault. I unchecked "Use for these applications" part. I thought I'd unchecked it but I was wrong.
