I can’t open the 3D warehouse when I’m in a SU file. I can open it and sign in if I go online but then SU won’t allow me to have two instances of SU open at the same time. I used to have several open at the same time but can’t now. It says my license is expired but it isn’t. So I have to keep closing and opening files to download from the Warehouse. Yikes!
They are probably updating the website. Try again later.
Couldn’t you open multiple tabs in a browser?
