Ok this is an easy one:
your error is [FMLMod:mcheli{0.9.3}, FMLMod:secretroomsmod{@VERSION@}]\
look in it the mods causing the error are
FMLMod:mcheli
and
FMLMod:secretroomsmod
make sure that those mods are both in the client and server mod files
if they are than are you sure you installed the currect version of the mod into the client and server (Client version for client, server version for server OR Universal for both)
if you have than delete the mods, should work
