After I installed a registry cleaner and proceed with it I think too much of my registry was deleted and the back up of it says that cannot import not all data was successfully written. Now my cd drive doesn't recognize a cd to record and doesn't read the name of it or anything. I'm able to open any cd, watch videos etc, but it won't record. And with all the registry deleted was all prior dates of which I could restore my computer.What can I do???
