Dude, where is my library?

I am a heavy user of Endnote as I am concluding my Ph.D. In the beginning of the year I decided put all my library inside a Dropped folder that synced all files between three different computers (2 MAC OS and 1 PC). They all have different versions of the program (9, x1 and x2) and today, after I synced one computer suddenly it stopped working. When I try to open it a window shows that the document “could not be opened”. Trying to repair and restore the library does not solve the problem. Can anyone help me?

I suspect that maybe the syncing process mixed files from older versions. Do you know someone I could sent my files to understand what happened?

I found a bunch of .es1 files within a folder called “Spotlight”. What is the fast way to recover them?
