I have just downloaded TI9 for a 15 day trial. I have tried to do a full backup of a folder (containing many other sub-folders) of 4.48Gb. It starts the process (very, very slowly!) and then causes the 'host' PC to lose it's network connection. This has happened 3 times so far. Both the host PC and the client (laptop) are running XP Pro. Does anyone have any idea(s) why this might be happening please?
