Thank you to Ken Hughes and bnt for your replies. Unfortunately my PC, in its wisdom will not let me uninstall .Net Framework 2.0 so that I can reinstall it. I have disabled my (Windows) firewall and it still will not behave correctly. I am reluctant to switch off my AVG (even if I could find a button to do so with) to see if that would help. Is it safe to do that?
Thank you,
