Open IE. Hold Ctrl + Shift + Del and clear its cache. Make sure you remember all passwords before do that.
Run Internet Explorer 9 in compatibility mode. To run in compatibility mode, click on the compatibility icon located next to the web
address bar. This icon looks like a piece of paper torn in half horizontally.
Try disabling "Protected Mode" using the following:
1. Close all open windows and programs.
2. Click on the Start button and then on Control Panel.
3. Click on "Classic View" on the left side, then double-click on Internet Options.
4. Click on the Security tab
5. Un-check the box for "Internet Explorer Protected Mode"
6. Click OK at the bottom, close the Control Panel, and open Internet Explorer to try again.
If this resolves the issue, then you might want to add Ancestry to your Trusted Sites in Internet Explorer. This will make it so that you
can enable protected mode for every other website but for ours it will be off. To add this to the trusted sites, go back to the options
and the Security tab, click on Trusted Sites, then the Sites button. Type in *.ancestry.co.uk, untick the "Require server verification"
box, and click Add. Then restart Internet Explorer and try again.
Let us know the results.
