YS menu help

(YSmenu) when i try to copy my Files from my 1gb sandisk to my computer it comes up with this error messege
An error occured, The destination you have specified does not exist. It might be an offline network or an empty CD or DVD drive, check the location again.it wont copy my files after this.

Check that the memory card is still in the pc and not disconnecting. That error message means that it cannot find the memory card when it tries to copy. Also you could try formatting

If you format though you will lose eveythink, its best to alway's keep a backup on your pc...

i do keep backups but the backup i have is like from a month ago

Back it up again, and format the MicroSD.
