What had happend ? , well … Easy (it is easy after 1 day suffering to try to find the answer). You have enabled another module(s) which is/are depending on the module you try to enable.
uncheck all module(s) which are depending on the module you try to enabled. then you can check the little dummy square radio button of your module. finally you got your module enabled.
Why this happens?
Because like in most of thing in this life YOU MUST BE ORGANIZED in order to achieve your goals
