Filters not working

I'm using Photoshop CS2 with several Nik Color Efex Pro filters
installed. The thing is, the filters are only selectable when I'm
working with jpegs. If I open a TIF image or a PSD file the filters
are greyed out and cannot be selected.

Is this correct, or is there something wrong with my setup? Shouldn't
I be able to use them with any graphic format?

Just incase it's my installation path, the plugins are installed in:

C:\Program Files\Adobe\Adobe Photoshop CS2\Plug-Ins\Nik Color Efex
Pro\

Thanks

The filter does not know and does not care what kind of file the image
used to be. When it is open in Photoshop, it is not a TIFF or a JPEG or
a Photoshop file at all any more--it is just a bunch of pixels in memory.

More likely, those TIFF files you have are different from the JPEG in
some way. Maybe they are CMYK, not RGB. Maybe they are 16 bits per
channel, not 8 bits per channel. Get them the same as the JPEG--same
color mode, same color depth--and your filters will work.
