*Giggles.* Actually, xilolee, I thank you for your assistance, but I have solved the issue today.
How? By using "Windows Repair (All-In-One)" from "Tweaking.com." It worked wonders.
Hi gabrielle!
1) Run sfc /scannow from an elevated command prompt, wait until it finishes, check the result (and send it to us), reboot your pc.
2) Copy the following text into notepad, save the file as W7SP1UltimateDefaultServices.bat (it should not be saved as txt and its icon should not be a paper), run it as an administrator, check if there are any error messages and paste them here... If there are no errors, reboot your pc.
