I have it, i checked it and i still got nothing, soo i guess i will just baypass

@Czan: Last thing I can personally suggest is your video codecs might not be uptodate. I recommend installing the latest K-Lite codec which is a program that installs the latest and most popular video codecs. Otherwise I'd check the FAQ for wallpaper engine which may contain a solution, see link in description. Good luck.

For example your https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1348680603 works just fine, but any of yours wallpapers from hellblade don't, can't figure it out, maybe some updates in wallpaper engine broke it, but i still don't know.

@Czan: I'm sorry my wallpapers do not work for you but that is not the fault of my wallpapers as they do work for myself and many others (otherwise I would have many comments saying they don't work). I did put a link in the above discription, did you bother checking it out? It gives many solutions regarding wallpapers issues/problems, it should describe your problem too and possibly give a solution. If I had to guess, the most common problem is trying to run video wallpaper at a higher resolution then your native in Win7 (unless you don't use win7 so its a different problem) which simply cannot be done, apparently an inherit problem with downscaling any video from a higher resolution. Howerver, if you say that you can view other 4K video (you didn't say video, perhaps you're viewing 4k scene wallaper which is completely different) wallpapers perhaps the issue lies somewhere else, again, check the link I posted. Hope you get it sorted.

Sry guy or girl, but only yours wallpapers from hellblade on wallpaper engine don't work, don't know why, and it's not becouse they are 4k, i have 4k wallpapers from FF15 and they work. Yours have only dark screen and sounds.
