crashing when i save

this is happening more & more now, when i go to save my beat, i scroll for the folder to save to, & it starts going slow, then the names go al distorted so you cant make out what it says.. then it restarts itself.. & i loose my whole beat..
have to make it again from memory,
anyone else have this problem cus this is **** serious

I don't think I've heard of this one before. At first, I thought it might be the classic saving/loading problem with Wrong File Errors, but the MP is restarting on you?

yeap, it startes going slowly when i scroll thro the folders, then crashes & restarts..
i have put my most imptortant files at the begining of the card, i.e 1songs & it doesnt crash, its wierd
