i honestly dont know how much that extra 0 matters but, yeah i would just copy and paste right from the tutorial since its the same. also you changed the format from : : to : . and that probably does matter.
i just checked my optimus.conf and i have it as 2:00:0 not 2:0:0 and its good so just put yours at 1:00:0
hah, its usually little things that screwing up the bigger ones. just make sure you didnt add or remove and characters from any other steps. done correctly this should work, dont give up
