Hi there, have been using MK picons as well as others on my boxes, but recently I've had some issue with picons not showing, or showing for the wrong channel, have used Flashfxp or Filezilla to tranfer from PC to usb on boxes, using SNP and some SRP picons, when I go to open some picons in usb get message "paint can not read this file this is not a valid bitmap file or it's format isn't currently supported, the picons are definitely PNG, I retranfer picon over and it shows, but then later gone again, this has happened now on two boxes, minor issue but frustrating, has my picons got a disease?
