Files stuck in queue

I've just downloaded and installed the new version of SmartFTP (32 bit version for Vista). And still I get the problem of files that are stuck in the queue. A whole range of files are transferred successfully but some files get stuck in the queue and stay there forever. The only solution is to close SmartFTP and re-transfer everything and hope no other files get stuck this time. Why does this happen? And how do I solve this?

Please double click the file that is stuck in the transfer queue. A log window opens. Copy&paste the log here.

This is what the log info says:

[16:49:07] PASV

Please post the complete log.

That's what the log says, nothing more.

Install the latest version and try again

Like I said in my first post I installed the latest version yesterday. I suppose there wasn't an update overnight?

What I notice is that when I keep adding the same file to the transfer queue, the third item in the queue starts transferring successfully while the other items stay in the queue.

Post the system information from the menu: Help->About dialog.
