Just downloaded the 30 day trial of WebStorm and was hoping to set it up to remotely connect to an FTP server for development but have hit this error.
"Connection to 'WACH_Supervisor' failed. Invalid descendant file name "/"."
Pastebin of the debug log: http://pastebin.com/GGxCPqR8
The only place that a "/" appears in a file name is under the cdir entry. But this is pretty standard is it not?
