I update my CFMU project to run on the latest Flex 4 framework which means you will need flash player 10 from now on. In the update I was able to fix a bug. If you are using the current project I suggest you update to the latest. If you had a list of files in the data grid and went to remove a file in the list it was removing the wrong one. Basically there was a problem with removing the wrong index. This was submitted to me by a user so thanks for the heads up!
