Yea, I'm sorry. LockOn has gone through numerous updates and patches and I knew it might be a little confusing no matter how I attempted to explain it.

If you have just "LockOn", then you have enough to get started with. It has the A-10A and is complete enough as it is. Don't worry about patching it or later versions including Flaming Cliffs. Just install that and give it a go - should work ok.
