I cannot correctly open the same files that were made a couple of days ago
I cannot correctly open the same files that were made a couple of days ago.
When opening, a window appears: the file was made in a NEWER version. Import this file? Part of the data may be lost

      Olena, which version are you using exactly? Please refer to Help > About Illustrator window to see the build number in the top left corner. 
 Is possible, please share the file with the team — send it over to sharewithai@adobe.com and put the link to this report (http://illustrator.uservoice.com/forums/333657/suggestions/47508290) in the body of the email so that they can track it here.Also, if you do try to open it still — do you succeed at all? 
 Does placing the file into a new document and embedding it instead helps? Will work only if you had PDF-compatibility enabled when saving a doc.
