Chenny, The forum should send you email when there has been an update to a thread you have started or posted to. I do not recommend revealing your email address directly in the forums as it could be bot-harvested.
One answer to your problem would be to use a tool like
Door and Window Builder which can handle the gothic window you want easily.
Or, for free, how about using an opening instead of a window? I think there is a gothic opening included in AC12. Have not tested this option....
