Hi RUC,
This post isn't very helpful to help you resolve your issue. Did you look at the log file to see what's in it? It's a hidden folder, so you'll have to grant yourself permission to see what's in the folder. Some places prevent folks from being able to do that. If this is the case, my suggestion is to try bringing it back up, after a few minutes, see if the error goes away. If not, try restarting your computer, then try again.
More than likely some services didn't exit properly and are creating unknown issues, thus creating the error you see above. If you still have an issue, please state what's in the log file, in order to better help you resolve your issue. Thanks,
