I fixed it but not by changing that pref, I had to move the incomplete folder out of the appdata directory, That was the problem. If anyone runs in to this problem you need to move the incomplete folder to a different location such as moving it into a folder in my documents. I set mine to /my documents/downloads/shareaza/incomplete and my downloads folder to /my documents/downloads/shareaza/completed, I usually do this anyway with all my other programs so i can find all downloads in one central downloads location such as /downloads/utorrent or /downloads/ftp
