Sorry to hear that.
1. Do you remember which version of Visual Assist were you using before you installed 1916?
2. If you press Alt+Shift+O, do you see all your files in the solution? (including the headers)
3. Can you please try
1. close your solution
2. rebuild your symbol databases
3. after the restart of Visual Studio, turn on logging (VA Options -> Performance -> Enable logging)
4. open your solution again
5. wait while VA is parsing
6. collect and send in the log files
You can read more about logging and where you will find the log files, here:
