I have used Camptune twice before to successfully resize bootcamp partitions. No significant changes in OS on either side (OSX 10.6.8, Windows 7). Camptune X 10.9 (I cannot even get 10.10 to run!). Today I get message: "Redistributing free space failed with error: No free space (can't create partition of requested size)", this is with over 70 GB free space on OSX and over 40 GB free space on Bootcamp. I was trying to increase bootcamp and decrease OSX by 10 GB.
