Encore Cs6 stopped burning DVD - all fail due to error 52102

I have been burning both DVD and BluRay and all of a sudden I cannot burn DVD anymore, They all fail with error 52102 showing up and interrupting the burning process.

I have tried to isolate the problem. I used different DVD brands, I used different projects, I used an external burner. Nothing helps. But i can still burn BluRay disks.

Any ideas?

Thank you!
