I have updated SportsTrak but it crashes when I try to open my old data.

Message might be:
“File daydtail.tps could not be opened. Error Invalid record declaration (47)”

Newer SportsTraks expect data to be in slightly different formats to older ones. Usually SportsTrak will automatically convert the data, but with some versions it won't.

To convert your old data yourself , download the stconvert.exe program and documentation from this link.

http://www.carobcom.com/dlstconvert.htm

Follow the instructions and use the stconvert.exe program to convert that data to be compatible with the latest version of sportstrak.

StConvert will create a new folder called NewData inside the old folder and place converted data into it. You need to copy that NewData folder and put into the SportsTrak folder with and aapropriate name eg SWIM2011
