I recently ran a pretty substantial PV calc using Ecotect. It turned out great. The only problem was, when I saved the file and closed it and then opened it again, the calculation data was gone. If I wanted to see the results or make any modifications (such as turning off a zone) I had to recalculate which takes more than a day. I was hoping someone knew how to open a file with the calculation data still there.
Thanks,
