I can't access to my team folder in grabcad

Hello! I am a student at Universidad Panamericana and I am working on a faculty project where we are using GrabCad as a file sharing tool. The project folder was shared with me, but when I open it in grabcad I get a message saying "You have not been granted access to this page." I discussed the problem with my faculty, but they don't know what could have been the cause, so they recommended sending a message to the grabcad support team. Could you help me with this problem? My account is supposed to have access to the folder. I attach an image of what is happening
