Out of the blue, I started receiving an error while trying to CrossLoop remote control my mom’s mac:

connection terminated
authentication failed incorrect  password

It was strange, because it worked last week, haven’t changed any setting, router, etc. It was a tricky error message, since … it shows up on the screen for about a second … Couldn’t find any help on support forum for CrossLoop neither, so i decided to do the support 101 myself … updated both my macbook & my moms’ iMac to latest version 1.4 … and it worked!
