Check to see which obj your saved cr2 referenced. With a little luck it'll reference an obj placed where the cr2 is and not your original obj. You can then alter the reference (remember a cr2 references the obj twice, search for .obj to get the second occurrence) to the original obj. And DO make a backup of it, if it's still there :o)
