You can hope that it will disappear with time. The same condensation effect can be on the lense of the reader.Unfortunately when a device decides to break it is not always helpful to know that it worked before flawlessly. Ĭheck if the reader is still working with other CD/DVD. If stored at a very low temperature relative to the user environment, the disc should be gradually acclimated to the environment in which it will be used to reduce stress and moisture condensation. This helped many times with the old CD supports and readers. In this case you can try deeply breathe on it (with a little intimate prayer to the soul of your computer) and clean with an anti-static cloth.
In presence of humidity in the air associated with a net difference of temperature DVD/computer inside, it's possible that some condensation effect makes opaque the DVD and difficult to read for the reader. In case clean with a soft anti-static cloth. You can see them better with a light searching for its reflection. The problem seems to be that the device is not able to read correctly the disk (if it is not a issue with the registry keys as suggested by another answer).
