Absynth 4 issues

I recently purchased a new computer to run Cubase 5… Everything installed and works fine, except for one small thing. When I bring up Absynth 4, it works fine until I close out the window for it in Cubase. After that, it still plays but the Absynth gui goes dark when I open it up again and will no longer allow editing. I’m not sure where the conflict is, but I think it might have something to do with the 32/64 bit bridge. Any help on this issue would be great, thanks.
