Cognos Configuration Utility Freezes

[jay3010]

Hello All,
     I am using Cognos Platform 8.3 with a content store running on Derby with data source mysql using a custom java provider authentication.
Whenever i try to open the cogconfigw.exe(tried with administrator) it freezes at the screen as attached in the screenshot.

I tried renaming the cogstartup.xml file, after which it loads the default configuration of Cognos on the utility after making changes when we try to save it freezes again, similary it freezes when testing namespace or content store connection.

I have also trird running the cogconfigw.exe with compatibility mode under XP SP3

Server is a 64-bit Windows Server 2008 Standard R2 Edition

Any help/suggestion would be really appreciated.

Hey Guys,
     I was able to resolve the issue.

Removed cogstartup.xml
Removed three folders csk.encryptkeypair and singkeypair from c8\configuration
Was able to open the utility and reconfigured it
Worked as a charm :)
