Can't find files on remote server

Dear SmartFTP support:

I've been using an ftp connection for quite a while to upload files, but recently it's stopped working. I'm able to login fine (userid and password seem to work), but it seems to stall out while looking for files on the server (at the "LIST -al" step). The ftp server is functional and there are files there (I can log on and see them via IE or Firefox). Any idea what's causing this? Is it something I can fix or is it an issue with the remote server? Here's the server, log, and other information:

Thanks in advance for your help!

Try to add SmartFTP to the exceptions in your software firewall.

You may also want to upgrade to the latest version:

since I have installed the version 3 I have exactly the same issue. on some of the servers I connect, I can't see any files or folders, although in the log I see there ARE files, no folder or files are shown on the remote server.

I use version v3.0.1026.24, I tried to edit the list settings in my favourites, and other trics I read, nothing works... could it be related to the fact that the server is running on UNIX? I have another connection on windows that does work with the same favourite settings. problem is related to the new version because 2.5 worked perfect.

this worked!

disabled MLSD in my default favourite setting
reconnected
first I had nothing on my screen, only the version number
but when I hit the refresh button, everything magically reappeared... finally

thanks a lot!
