Using an old version of SA:MP won't be a good idea. Simply because all the servers have been updated within the few days of the new client being released, and no one will join yours to be perfectly honest with you. Too much effort, anytime they want to play on your server, they've got to downgrade their client and then when they want to play another, again, update their client.

I'd recommend you find some sort of alternative for OnEmptyVehicleDamage, or not use it all, and I'd recommend you use 0.3x (the latest version).
