Can't solve the problem with meteor, help please!

I work under windows 7. After creating new file and starting it i see this:

=> Started proxy.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Can’t start Mongo server.
MongoDB had an unspecified uncaught exception.
This can be caused by MongoDB being unable to write to a local database.
Check that you have permissions to write to .meteor/local. MongoDB does
not support filesystems like NFS that do not allow file locking.

You may find something to help in this SO post (there seem to be quite a lot of potential fixes):

It could be related to the latest update of Meteor.
See, Meteor 1.4.2.1 is an important patch for 1.4.2 users

(I use Meteor with Windows 8 and 10 and got also Mongo 100 error after ‘Meteor build’ of a brand new created Meteor app)
