As suggested, Filezilla might be worth a try, it tends to give more information regarding errors if nothing else. It might also be worth trying without any firewalls or antivirus active, just to eliminate them from possible causes.
If you get any information back regarding the error, please submit it as a support ticket via our help and support pages, and I'll take a further look for you.

Are you using standard or VIP hosting?
FWIW I use FileZilla as my FTP app (it's free).
Over the last few weeks I have noticed a few FTP hiccups myself on standard hosting - mostly on web server 5 (as that's where I frequently upload).
The files timeout and the transfer fails or I've seen a few very slow transfers - tiny files that take minutes to complete.
I've found that retrying later in the day the problem has gone and normal service has returned. Things seem more stable at the moment so I haven't raised a Support Ticket but I'm keeping my eye on things.
[s]Hmmm...[/s] I cannot help you explicitly, but a Staffie or Hmmm may spot this post at some time ;¬)
However, you give very little detail of your specific problem. I have no knowledge of Serif software ... I use CoreFTP for uploading and I've just checked all my sites and they are all accessible ... and all are on different servers! So just maybe the problem is at your 'end'?
