Hi all

I accidentally had my memory card on "lock" so didn't record my session. I downloaded the Navilink and got most of the session, except for the last 1/2 hour ( I hadn't cleared the memory before the session) So I thought I'd save the data logger, which I did successfully, but when I open the file with realspeed, it does its little calculation in the bottom left corner but then displays this:



Any suggestions? Do I need a different version of realspeed to read the SBP file?

Any help greatly appreciated
