My AV and Firewall have not changed, I have un installed and re installed the FLogger, the only difference being that I have installed it in the default Drive C which is where it asks to be installed, whereas before I had it installed in my Drive F which is where I have my Flight Sim installed, I have logged into the FLogger 4 times and all have been successful first time, I don't know why this should be, I will let you know if it continues to be OK.
