I'm using SW 2013-2014 with a student license, but since for the coming 6 month I will be working together with people using the 2011 version, I will have to work in this version too. Is it possible to use this version with my newer student license and where should I download this version?
Are you looking for the 2011 student license or are they using a commercial version of SW2011. If it is a commercial version you will need to be careful that you stay "legal". I don't know if SW2011 is still available. I would start by checking with your SW VAR (the company that supplied your student license).
