Advanced Glass Shader

I’ve just spent an hour trying to load the glass shader into projects that I had it already in there so i could get axcess to the blurred glass and it keeps deleting files I had in there like the map and the mat_glass and nothing in the blurred glass . Tried this on 2 computers in multiple projects - half the time it says it can’t load over some of the assets then the mat_glass dissappears and they no longer work ??? any ideas

projects that do not have it in it and not all loads - no blurred glass no mat_glass no map - ///4.17
deleted off hard drive and aded to project from marketplace as well
