For those of you having trouble making co2m8 work for you I would suggest the following steps:-
a) make sure you have the correct version of co2m8 for the CO client your using.
b) read the co2m8 threads, there's 2 of them(read backwards starting at the end)
c) read the instruction thread

yes its old and a bit out of date but good enough to give you the gist of it.
d) if your still stuck then post a question on the co2m8
Please don't sent me private messages requesting help on how to run the program.
Big thanks to all for your support of the co2m8 project.
