I may not be saving the files correctly...
I tried to download and read it and can't get it to work for me either. lol
Ah hah.. I think what you need to do is... right click on the link and save the zip file to your computer. Once it's downloaded, click on the zip file to open it and retrieve the .dat file. Start the powerlogger console, click "load" and select the file you just pulled from the zip folder. Click on the gage console or data console... then hit your right or left arrows to move thru the saved data.
