Hi guys,

I copied some pics to my computer, and i use ACD to open them then set one of them as my wallpaper successfully. The ACD is activated, but when i restarted my computer the wallpaper is gone and the wallpaper became black! My system is windows 8 home basic.

I don't know what's wrong with this, so i want anyone who can tell me how to solve this problem. Thanks a lot!!!
