I have updated my firmware to version 15, which was originally 14. It worked very well after that for several days. then suddenly when I was trying to back up the phone memory to the card a message appeared saying " Memory Card system error", then, I tried to backup thephone using the PC suite, also, an error message appeared saying that C(phone memory)failure. In addition to these faults when I access the application "JAVA Ctrl" an error " App. closed MidpUi", which preventing any installation of any Java applicatio. Please tell me as soon as possible waht to do to fix this problem.
I think I might lose some application and system files such as MidpUi which stoppped JAVA Ctrl application. How can I retrieve my system anf builtin application files?
