Are you a Windows 10 user? If so, the problem was caused by the recent Windows Update - most Windows users automatically installed a new security program on January 9.

Some G5 players said that rolling back the Windows Update works. However, the same problematic program will be automatically reinstalled unless you turn off the auto update function on Windows Update.

In this case, you had better report the trouble not only to G5 but also to Windows because Windows is the only one who can fix the problem. And please bear in mind that it may take a month for Windows to fix it.
