Xojo with .rbx plugins

I recently had a customer download one of my plugins, and he advised me that he could get it to work with RealStudio, but not with Xojo. I was under the impression that the old plugins (.rbx) would work with Xojo? Is this correct? And if it is, is there any special configuration steps that are necessary?

Old plugins should still work. Just drop them in the plugins folder.

Thanks Christian! BTW, still using your MBS plugins, they still rock.
