Hi, Ed! Looks like the site is down this morning, as I could not post a reply to your message on the UFt boards.
You can find the downloadable upgrade at this site (look under the links tech support and downloads or something like that) http://www.uftree.com/http://www.uftree.com/
The error 43 message is an "insufficient memory" message, usually occuring on fast computers when going to certain lists. There is also an update for this, depending upon what type of system you have. Usually, it shows up when you are looking for place name or something like that. The program only displays 250 records at a time. If the record you want is not in the list, type part of the name in the field at the top and click Find Again.
