I've been trying to setup my computer to run DataLogLab. I'm running Windows7 Ultimate and I finally got my laptop to communicate with my Link. I was able to take one datalog with the car in my garage. Since then, every time I try to open a new file I get "Unknown file system problem." I changed my administration settings so that I have full read and write access for Data Log Lab but the same error keeps popping up. I've also tried uninstalling and reinstalling DLL. Still no luck. Any advice? Thanks.
