I want you please to do a system restore to undo any corruption that has occurred.
To do this, right click on the windows logo in the bottom left and click on Control Panel.
then click on System and Security
Then on System
Then System Protection
And click on System Restore.
Follow the onscreen steps to perform a system restore, choosing the last restore date.
Let this complete and when it has tell me if you still have the issue please.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know the results.
