I purchased S&T 2009 two years ago and have planned and saved 6 trips on my hard drive. Today, when I tried to open several of these files using S&T 2009 I couldn't and received one of the two following error messages:
"An attempt was made to access an unnamed file past its end."
"This file was created with an older version of the map which is no longer supported. Please consult the help documentation for further details."
I couldn't find any documentation in the help files.
PS: I reinstalled S&T 2009 and still received these same messages after a complete reinstall.
Do I have to buy a new version of S&T every year it is upgraded in order to use older saved trips?
You should be able to use files created with the same version, indefinitely. Also, a version of S&T or MapPoint will be able to load older maps from 2-3 of the preceding versions, although there is a cut off - eg. MapPoint 2010 cannot read maps from
Is it possible you created these files with an older version of Streets & Trips?
