Error - Could Not Get File Size

[PhoenixNc]

I'm ftping the contents of a documents directory to my online file folder space from GoDaddy. I have the file overwrite settings set to overwrite on upload if file sizes are different.

The problem is that every single file size comparison for the transfer generates a could not get file size error (excerpt below). I used Filezilla to upload files initially and it did not throw any of these errors. (It couldn't handle large files though and that's why I'm testing out flashfxp)
