Download from this sharefile api produces a zero size file

[chamberlandmi]

I have used the github example https://github.com/citrix/ShareFile-NET to create this program that will downlaod all files in a certain shared folder of mine. It seems to work ok when the files are new, but if I upload them a secondtime after deleteing them, then the next time I try to download with my program, They end up on my local machine with zero file size. ( the file is created, but it is empty) I can't tell why. does anyone have any ideas?
