Hello ! I don't know how this happened, I was cleaning some stuff on my computer, in my sdata partition, mwhen I noticed some blank Icons in the task bar, it was the windows explorer icon, and media player that turned blank. Afterward, I noticed that my libraries didn't expand anymore, I restored them... But I had lost all the folders I included in different libraries. Then, all my programs reacted like if I was using them for the first time : firefox asked me to import bookmarks, itunes to import music etc... Consequently I've lost all my bookmarks, my plugins, recorded passwords etc. Same for msn messenger. An idea of how this happened ? How can I restore those datas ??
