I am using standalone, PC based- windows professional 7 IHS KINGDOM. While opening the project, gets the message about SQL express server , which is too quick to read and than the project disappears from the list. Why this happening? how can I do the back up of the remaining projects?

Let me rephrase my previous Q. While opening the project the small windows opens asking “SQL SERVER EXPRESS INSTANCE U SELECTED IS NOT RUNNING” DO U WANT TO START THE SERVICE NOW ? YES OR NO.
