For some reason I am unable to import shape files in the form of point data to REDCAP. Do these data points need projected coordinate systems? I am aware that the sample size is 500 when double clicking the REDCAP file.

I am also encountering errors when using the command line to launch the application.

Java is not recognized as an internal or external command when trying to execute the code included in the manual.

Any suggestions would be much appreciated.
