The Dink Network

I've downloaded WinDinkEdit.plus and some tutorials to learn how to make a dmod. It all worked fine on windows xp. Now, on windows 7, after few minutes, message shows up: this program has stopped working blah blah blah, close program, or find solution on internet. You know... usual message when something is wrong. Well, how to make it work again? And how long does it take to learn how to build a dmod? I only menaged to create a crapy house interior and script four objects in it, after two hours.
sorry about my english.
