Hey, i'd usually search before writing the problem but this time its a very strange, all these problems occured suddenly:

-File manager shows: No files/folders.
-System uses a blank gray theme.
-a lot of application icons turned into blue square.
-When trying to disable an app. catalog it says: Internal error, Application manger closed.
-when i try to open the main menu it suddenly closes.
-when i click on a video/audio file nothing happens, it doesn't open.
-most applications wont open when i click on them.

i have 16mb free rootfs space at the moment.

last application i installed is OpenJazz game.

is there anyway to solve these problems without reflashing? how can i know what causes them
