I upgraded from Vista to Windows 7 and since then the SQL Server 2008 SP1 Management Studio Package is broken. Whenever I start it, it just shows the message "Package 'Microsoft SQL Management Studio Package' failed to load". and closes again immediately after clicking OK.
SQL server itself is still running fine, I can still access it from my web app.
Any idea what might be going wrong or how I can fix this? Would a re-install help? I was careful to update SQL Server 2008 to SP1, so it was supposed to be compatible with Windows 7.
