For some reason ,I get something wrong on software .I wanted to get update one day .It showed that there are some errors so that I can't get update .the software libqt4-core,etc.
needs the newest version , but I got wrong vresion from maemo.org/packages .Now my software based on libqt4-core on my n900 such as sib,KMPlayer ,filebox...can not work.when I click the icon , it would quit immediately. I reinstalled them ,however ,it's no use !What should I do now???
