I am experiencing this error message on my SQL Server:

Invalid database file version

The .MDF in question was working previously.

How can I fix this because the information in the file is very important to me?

Post the actual error. Your interpretation of it omits critical information in that error message. – Remus Rusanu Aug 14 '12 at 9:12
Additional information would be helpful on when/how the error is being generated (your trying to attach the database to existing instance, moving it from another instance, your server crashed and you are trying to recover)? – Shawn Melton Aug 14 '12 at 12:40

Without the actual error message I'm just guessing here...

Odds are the database you are attempting to attach is newer than the version of SQL Server that you are trying to attach it to.

For example you have a SQL Server 2005 instance, but the database file was last attached to a SQL Server 2008 instance.
