XCode CoreData files not found/opening
I am using the Xcode 3.1.4 that means SDK 3.1.2

The problem is that I cannot open .xcdatamodel (Core Data) file and I don't even get the Data Model option in Design Menu bar.

When ever I double click and try to open the file, 
**XCode gives me an error saying that it cannot find the file at (my project's path).Perhaps it was moved or deleted?** , but the file exists at the same path.

Please help me out as I haven't upgraded my system to Snow Leopard so cant use SDK 3.2
