I have successfully installed Level 13 (3.2) during the Android SDK installation, but chose not to include any earlier levels at that time.

I now would like to install 2.2 or 2.3, but in the SDK / AVD manager I get the message:-

> 
> Failed to fetch URL
>  <https://dl-ssl.google.com/android/repository/addons_list.xml>, reason:
>  File not found
>

I've looked this up in other posts and so run the SDK manager with Administrator permissions, and have turned off the firewall. Eventually, it comes back with SDK tools revision 15, and SDK PLatform tools revision 9 only.

1. Should I have installed earlier packages during setup?
2. Would an uninstall / reinstall cure this behaviour? (Reluctant to do
this :-( for obvious reasons)
3. Is it possible to get earlier levels having installed just level 13?

Any help would be greatly appreciated. Thanks for looking.
