unable to start Rational Software Architect [eclipse]

Question

I have updated the eclipse [3.6 to 3.7] of rational software architect. After updating it I am unable to start the rational software architect, although the window task manager showing a process with name eclipse but nothing is appearing. When I enabled the consoleLog it showed me following message and it started

Could anyone suggest what should I do to achieve the normal startup.

You probably have more versions of same plugins. You should remove older versions. Perhaps it get easier for you to do a clean install of everything.
