Hi,
This was happening to me. Ofcousre it was happening after I killed the E*gate manager in the task management. Then when I try to open the e*gate manager then it used to say "Loading the schema ..." and it never loaded [hanging]. It was due to a java program [editor program running when I saw it throgh the task management]. When I ended that program, it started working fine. In your case if this is happening at the first time itself then I think you need to reinstall the software.
Hope this helps. Let me know how it goes.
Good luck
