interface FastEthernet4/1
ip address 10.10.0.46 255.255.255.252
ip ospf network non-broadcast

In the posted solutions i haven't seen where you actually confirmed that MPLS is indeed running on your tunnel interfaces
sh mpls interfaces will show you the current status of the attached interface.
This is a critical step before verifying any thing else along the path. If your tunnel interface is displaying no or nothing under IP, run the command under the interface mpls ip then secondly you can hard code mpls label protocol ldp if you find it fitting.

Harris,
Replace the word Loopback1 with the IP Address /32 mask

Just disable igmp snooping on the middle switches.
If you are having connection through switches then this solution can help to bring the LDP neighbor ship up immediately.
