我想从lightswitch连接到sql2008 express。我想一个简单的表格，但每次我试图挽救，我得到这个错误：Lightswitch连接到SQL问题
The underlying provider failed on Open.
Inner exception message:
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
我检查SQL日志和下面是我得到的错误：我查了一下
