I upgraded iFolder from 2.0 to 2.1 and the server side went without aproblem. The next time I logged in, I was prompted for the client
upgrade and after rebooting, I got Authentication (-87) errors. I
remove the client and reinstalled and got (-105) errors. So I removed

the 2.1 client and installed the 2.0 client and it works fine. What
they change?
