I can use SportsTrak to open my old data but newer data sent to me by my interschool organiser gives the error
File daydtail.tps could not be opened. Error Invalid record declaration (47)
Your version of SportsTrak is older than being used by the interschool coordinator
Firstly download and install the latest version of SportsTrak2100.
To convert your old data, download the stconvert.exe program and documentation from this link. http://www.carobcom.com/dlstconvert.htm
Run the latest version of SportsTrak you just downloaded.
Set the data path to the data you wish to work with.
If SportsTrak crashes on any file, then use the stconvert.exe program to convert that data to be compatible with the latest version of Sportstrak 2100
