[CE12]Assign Main Task?

I'm not sure whats going on with this one. At home when I configured my CONNECT installation to use my V8i tasks everything showed up however I am in the office today and have done the same yet my Main Task is showing the default Main Task and not my own. I've gone into my dgnlib where the task is configured but there is no option in the Customize dialog Properties section to allow me to assign the Main Task.

Any ideas?
