I have a design library folder within PDM that holds a lot of sketch blocks. Recently the files are "not found" as you can see in the error message below, but the file location shown in the error message is correct. The blocks have not moved, not been changed, nothing to break the link that i can think of. Some of these have specific size ratios (like UL marks) and i put them here so that they are available to everyone and they don't have to rebuild these marks every time one is needed. I really need these to work like they have in the past, can anyone tell my why these file locations are failing to link to my design library folder?
