Thanks again for your help, C: AMIE !
Turns out all I needed was LOTS of patience...
It only took 2 hours 15 minutes for the install to get to the point where it says "Updating your system...".
It was fairly quick after that point to finish the install!
Connected up my new Sig3 and it connected with desktop right away!
So far works great and I'm almost finished converting the Sig3 to English. I'm following the excellent instructions and file download from the Yahoo HandheldPC group by a guy named Steve.
Onward and upward!....
