Sansa Clip+ Firmware Update 01.02.18

Hello to all. I have the clip+ 8gb. I´ve noticed when I use a SD card with less than 8gb, the player sometimes hangs, and the player doesn´t like the 4gb ones (hahahahahahaha). After the update (last year, approximately 10 or 11 months ago), the same thing. I´m using the 8gb sd card since then, and no problem appeared. Thanks.
