Unable to open 2 options under Requirements Engineering module installed

I have successfully installed Requirements Engineering and all other modules are functioning properly.

But when I click on "Requirements" and "Requirements Document", I get below error message:

Note: The "Graphics" option under Requirements Engineering is working properly.

I also tried un-installing and re-installing RE module but no luck (all other modules are working fine except these 2 options under RE).

Please help to fix this.

Server Error in '/InnovatorServer/Client' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.

Details: To enable the details of this specific error message to be viewable on the local server machine, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off".


<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="RemoteOnly"/>
</system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="On" defaultRedirect="mycustompage.htm"/>
</system.web>
