Thx Max,
You are correct, I had a _2 before, and just changed to the _3 to make
sure I wasn't over looking something and forgot to change that back. I
found a work around for now but I'm still getting the error on compiling
in VS 2010. This may be some quirky problem with 2010 I'm not sure, as
soon as I find the solution I will post it up here.
Off topic:
Love the work you guys at Unknown Worlds are doing and have done, hope you
guys take the world by storm with NS2 :).
