I started up the Construction Set and tried to edit my mod. After pressing save and nothing, happened, I pressed save again and I got a message saying the other saving process wasn't finished yet. I tried restarting the CS and it still wouldn't save. After that, I tried creating a new esp. After making my changes, I pressed save. This time after naming my file I got an error message. https://dl-web.dropbox.com/get/Error%20%282%29.jpg?w=1f721408 is it. Abort Closes the CS, while retry just brings up the message again. I don't know about the ignore. Any help? This is the first time ever having this issue. I haven't use the CS in a long time, butI haven't changed any of the files, so I'm not sure what happened.

Link to error message just tells me I don't belong here, and maybe I should log in...... (I don't have a dropbox account......)

What operating system, where is the game/cs installed to?
