I was working on a file all day long. Auto save was set for every 2 minutes as always. At some poin I started closing preview tabs I was no longer working on, I had quite a number of them oppened, and to my surpise the tab I was working on was no longer oppened. Lets say I closed it by mistake, I have worked in Illustrator for years now and if that were to happened all I had to do is go back to the folder and re-open the file and continue working. Now, here is the question, I went back to the folder, re-opened the file and to my surprise again all the work I have done during the day was reset to the previous day. Can somebody help me to recover this file?
