Same problem here. Autodesk you should fix this. First i get the parameter name length error in logging in to the green building studio desktop program. Then i also get error when I reach page 3 of create new project. I saw that I might need internet explorer 6 to bypass this. But its not possible to install on windows 7!
Why dont you upgrade your service to work on all web browsers?
And what is this parameter length error!?
