MS PROJECT gbui://mainpage.htm/ Fixed

I was fiddling

I was working on Project and suddenly this error took me to nuts

ERROR :- The command is attempting to use a webpage from the site gbui://blank.htm/. You have not identified this site as a trusted site in Internet Explorer.

Microsoft Project cannot display pages from untrusted sites, so we cannot execute this command. If you want to use pages from the site gbui://blank.htm/ in Microsoft Project, you need to make this site a trusted site in Internet Explorer. You should make a site trusted only if you are sure of the site's identity, and you trust the site will not attempt to damage your computer or your data. Note that when you trust a site in Internet Explorer, you are trusting the entire domain to which that site belongs. For example, if you trust the site http://www.microsoft.com/widgets, you are trusting the entire http://www.microsoft.com domain

Method 2: Add the GBUIDisplayToggle registry key value in the registry

To add the GBUIDisplayToggle registry key value in the registry, follow these steps.Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
1. Click Start, click Run, type regedit , and then click OK.
2. Locate and then click the following subkey as appropriate.
For Project 2002:
HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\MS Project\Options\Interface
For Project 2003:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\MS Project\Options\Interface
Note If the Interface registry subkey is not listed under the Options subkey, you must create the Interface subkey. To create the Interface subkey, right-click the Options subkey, point to New, click Key, and then type Interface.  I couldnt find INTERFACE in my regedit and I created it and it worked fine
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type GBUIDisplayToggle, and then press ENTER.
5. Right-click GBUIDisplayToggle, and then click Modify.
