I am using a timer to update a SQLite database every 5 minutes (using the database toolbox) with new data. This timer is supposed to run continuously every night. As I came back to my computer today, Matlab had stopped (out of memory exception). I now cannot connect to any database, or open the database explorer, or edit the database toolbox preferences as I get this error systematically:

Error using javaObject
No class com.mathworks.toolbox.database.databasePrefs can be located on the Java class path
Error in setdbprefs (line 58)
DatabasePrefs = javaObject('com.mathworks.toolbox.database.databasePrefs');
Error in database>errorhandling (line 399)
switch lower((setdbprefs('ErrorHandling')))
Error in database (line 118)
        errorhandling(connection.Message);
