V8i SS3 - Cell Selector Will Not Load

Greetings-

I'm trying to use Cell Selector with MicroStation V8i SS3 (08.11.09.397).

I cannot get it to open; all it will ever do is open this dialog asking for a Cell selector file:

I do not have a CSF file but I would like to create one.  My understanding is if there is no CSF in the directory specified by MS_CELLSELECTORDIR, or if it is undefined, Cell Selector will load the library attached to the current DGN  (if in fact one is attached).  I do have a library attached to the DGN.

Other things I have tried:

• I have attempted to use Cell selector in multiple files.
• I have attempted to use Cell Selector with different clients (configurations/microstation environments).
• I have attempted to load Cell Selector from the menu (utilities --> Cell selector), by mdl load cellsel keyin, and by mdl silentload cellsel keyin.
• When using the keyns, I have tried it both without a filename following (I do not have a CSF to keyin), and also with a Cell Library in the keyin field.

All of these attempts merely gave the dialog above; Cell Selector did not open.

In the dialog asking for a CSF, I have tried both the "Open" and the "Cancel" buttons.  Clicking either does the same thing: nothing.

I have also tried setting the filter to files of types *.* (All Files) and then browsing to a cell library.  When I do that, nothing happens.

Every attempt to get Cell Selector Open does not work for me. Other users at this site have this same issue; we have a mix of SS2 and SS3 install and either version exhibits this behavior. I have got to be missing something... I'm open to any suggestions.

Thanks!
