Lock-up on LIST -a

I just upgraded to your latest version and now when I try to connect to my site I get the following:

Opening data connection IP: 0.0.0.0 PORT: 1103.
LIST -a
425 Can't build data connection: Connection timed out.

It locks up on the LIST -a and then after a while, times out. This used to work just fine prior to the upgrade.

HELP!!!

Go to tools, settings, connection and on data connection change the port ip mode to auto, if no luck change to manual and write your ip.
