>Well, something nasty happen last night. Because when came in the office this morning I discovered that SQL Server Report Builder 3.0 crash when I try to launch it. No particular error, just says it can not start. I have uninstalled and reinstalled, but the problem remains. I am running Windows 7 enterprise. I have been using Report Builder for over a month without any problem. I am at a complete loss as to what maybe interfering with the startup of the application.

Have you tried looking at SQL Server logs and Windows Logs? Have you installed any Windows updates?

I also recommend this forum http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/threads - you may get an answer there much quicker.
