Meet management made simple.
I am having the same issue. I've tried it on 3 devices - 3 networks - and turn all firewalls on and off. No idea how to log into RaceTab?!?
I've had people use older versions of the software when they run into these types of problems. I prefer to have schools set up their own meets and I just run a timing camera. Several schools still use V3.49, it seems to work well and on older "disposable" netbook computers that don't get put on the schools network
