Excell macro suddenly stopped working

[ChrisDemo-lab]

I am using for many years now RefProp7 and I have several folders (which include the fluids folder, .ddl file etc) mostly for calculating fluid densities. Everything was working fine until today when I pasted some new values and I got the #VALUE! error. I tried different files and folders and it seems to have crashed everywhere. I also checked the refprop excel file and it is not working there either. The actual refprop software is working though. Any idea on what could have happened?

Hi, Version 7 was a looong time ago (2002 ?) but maybe you can find something that is useful here https://pages.nist.gov/REFPROP-docs/#resolving-problems-linking-with-excel
