Today while editing web. dropped out of the project for a second function starts. Of course, I turned off the PC. After starting the PC and hammer the website and selected by adjusted web.projektu I have a project can not be opened. The screen lists the message: This project is used or not properly closed. Do you want to continue?  When you click on OK to start the download, and within a few seconds declares: Error while recording project. Is there any reasonable way to make it work? Other projects I opened smoothly, except for one that I had open during a power outage.
