Unblocking macros CoolProp

[CalmCollected]

Hello,

This schoolyear I need to use CoolProp - A Excel database of fluid and humid air properties for my minor. The problem is that I'm not able to unblock the macros to get access to this feature, because the source is not trusted. I've tried all that I know (changing macro settings), but I still can't seem to find a solution for this problem. 

Any ideas how to solve this problem?
