#61 "Update components" option do not working on Fedora Linux

[nokia808]

Hi. I'm already installed xdman on my Fedora Linux. It is version 7.2.7
I noticed that there is new version 7.2.8
I tried to use "update components" option but it failed. It download about 14 mb but it seem failed to applay them because it still can download the 14 mb each time I use it as if not applied them after each time. Is this normal on Linux & I should make remove then fresh new installation of package ?
