#1 ProsGui won't assemble downloaded file

[Anonymous]

I'm using ProzGui v. 2.0.4 beta 3 (static build). I
downloaded a .iso and when all parts were completed I
received an error message about not enough space on
hard drive. I have taken care of the disk space
problem but now ProzGui shuts down when I try to
finnish this download (assemble the pieces). Please
tell me that I don't have to start the whole download
again (a three day task).
