Your problem sounds a bit like the descriptions in this thread. Maybe you could read up on a few of the last comments to get a better picture - to see if it fits.
For many users the solution to the problem was a downgrade of the software from version 6.14 to 6.13.
Do you know which version you are currently running?
Of course it could also be a one off problem caused by something completely different. Did you change anything on your computer or the connected devices recently?
