Moving partitions around without image backup is gambling. I would boot the partition manager and see if it has an "undo last operation" function to get back where you were. Then back up before trying anything. Another thing that can restrict how much you can shrink a partition is file fragmentation. Before attempting to shrink a partition I defrag it.
