Multicast - a bit clueless!

Ok, I am now into multicasting, and I am having trouble confirming my
work. This is IPE Section 17 (for anyone who has it). Here is the
topo:
 
            /-----R4
R1-R2
         | \
         | \
       R5---R6
         | /
         | /
         R7
         |
         R8
 
 
Routers 1and 2 are connected via Ethernet segment. R5,6,7 are as well
(different segment).
 
Problem 1
This error message appears on R4:
r4# %PIM-6-INVALID_RP_JOIN: Received (*, 224.44.44.44) Join from
150.50.24.2 for invalid RP 150.50.24.4
 
Also, when I ping 224.44.44.44 from R2, it looks as though R5 is
responding:
r2#ping
