Uploads fail via Global Queue

I have no idea why this is happening. I'm not even sure this is a bug, but i see no other adequate section to post it.
The problem happens when i try to upload a folder with some php files and subfolders in it. Smartftp uploads the first 4 or 5 files, and suddently stops uploading, with the following message in the file status in global queue: "Waiting to retry".
I don't know what's causing this, and i have no way to find out, since there is no transfer log in global queue. The ftp server is working fine, it's on my hosting company.

What should i do? Upload the files using FlashFXP?

BTW: Drag'n'dropping the folder to the ftp window will result in an incomplete upload. Session queue won't upload the complete folder content, too. All of these queue/transfer method seem to hang at the same point.

edit: typo

Try downloading the last development build, it has some fixes about global queue.

Where could one find the latest build because I believe I have been having some problems with my program too.
