I stumbled in an error while calculating room loads for a LEED certification. Model was made with 6.4 version, then I've upgraded to IES2012 and today, while notice that "replace" button was grey in Baseline case, I've installed hotfix2. Now I can change Baseline constructions but, at the end of load calculation I have this error:

I've rebuild the model in model settings and recalculate shading file but nothing has change. Error message reports a way to fix Cliopenings problem but I don't understant what is "key-in box".
Thank you in advance,
dani
