I just installed Windows 7 on my Macbook Pro via bootcamp. I installed revit through my student account and now I am having trouble keeping it open. It will let me open a document and look at it for a little, but as soon as I try to start building something or adding to an existing building the program shuts down and closes. It opens up a box that tells me to send you an error message. I need help with seeing if I have the right requirements and so forth.
