Filezilla is unable to connect to my FTP server

[John Legg]

I just updated Filezilla to the latest version and since then it has not been possible to fully connect to my FTP server.

Here is a copy of the log window:

Status: Resolving address of 31.193.5.45.srvlist.ukfast.net

Command: MLSD

I have been using FTP daily until performing the upgrade.
