Not Enough Disk Free Space

here's something new happening:
favorite - with passive ftp and noop enabled (i am behind a nat)

on transferring files, the first file transfers fine but then as it tries to start the next one in the queue, i get an error message pop up window of 'not enough free space on disk'.
this is random...the disk i'm transferring to has over 300 gigs free and the file size is about 6-7 mb.

What version of SmartFTP are you using? This looks like a very old build. Please install the newest one from:
