The problem is a Privacy Settings issue with Internet Explorer as to how cookies are used what information you want to allow them to store.

One option around this is to lower your privacy setting to be less restrictive.  The safer alternative is to expressly allow cookies from specific website that you know and trust.  Below is a brief tutorial on how to easily do that.

1 - Click on the Tools dropdown on the menu bar of your Internet Explorer.  Mouse down to the Internet Options setting and select it.

2 - Select the Privacy tab.

3 - Click on the Sites button.

4 - In the Per Site Privacy Actions form, enter in the address of our host site, which is DigitalRocks.us as shown below.  Click on the Allow button.

5 - You should see digitalrocks.us with a setting of Always Allow in the Managed websites area.  You should now be able to login.  Click on OK to close this setting page.
