Yes that's fixed that thanks very much.
But now I've lost all the backup schedules that I had set up.
Do I have to re-schedule these?
I have just upgraded to 4.2.145 on my Vista PC. Now when I start the software it just opens a blank window, at which stage it freezes. I then have to ctrl+alt+del to close it down. I have tried rebooting and re-installing but I still get the same problem.
