NIOS II Perspective?

Thanks for the reply, but that was the point of the post. There is no Nios II option within my "Window | Open Perspective | Other...". When I originally installed the tool this options was available as was the option to simply do "File | New | Project | Nios II...." However, for some reason all of the Nios II awareness seems to have gone away. Since the Eclipse tool is a generic IDE I imagine that the Nios II capability is defined in an XML file somewhere. The odd thing is that when I removed the Nios II software and then reinstalled, with the same file that I originally downloaded, I still don't have Nios II support.
