Thanks Rich and Mike, I got the copy you sent to Dropbox.
It would be nice to know what went wrong with the SU download. I just switched to Windows 7 and maybe there's a security issue with Firefox that I am unaware of.
Just for fun I tried to download Catchup 10 using Internet Explorer. Both the Open and the Save options worked fine so the problem must be with Firefox where both options fail.
Regards,
Don
