I recently received an error that Skype could not log in due to a disk I/O error using Windows 8.1. I found this odd since there had been no previous errors with Skype or dirty shutdowns or reboots of the computer.
I tried restarting my computer and following the instructions at
which did NOT resolve the issue. To solve the issue I ended up doing the following:
- Opened the task manager and terminated BOTH the “Skype application” task and the “Skype background” process
- The Skype help instructions point to a path of %LOCALAPPDATA%\Packages\Microsoft.SkypeApp_kzf8qxf38zg5c\LocalState\ which for me was totally empty so instead I backed up and then deleted the files and folder located in %appdata%\skype . If you get an access denied error trying to delete this folder make sure the background skype process from step 1 has been terminated.
- Delete the contents of the %temp%\skype folder (again will give an access denied error if both tasks from step 1 have not been terminated).
At this point Skype magically allowed me to log in and started working again.
