Zedge was working fine until recently. My installed ringtones disappeared and I can no longer download Zedge ringtones, getting the message "download failed". I can download notification sound and wallpapers okay but not ringtones. I tried uninstalling and reinstalling Zedge but still have this problem. My phone is HTC Desire A8181 and I have a 8 gb card installed, which is almost empty. Can anyone help?
