If you haven't recently restarted your computer or you don't restart your computer very often, we recommend that you restart your computer. This helps clear the internal memory (RAM), which often resolves many issues.

Troubleshoot your internet connection

The issue could be your internet connection. For help troubleshooting your connection, please visit the appropriate help article below depending on your connection:

Uninstall and reinstall the AOL software

If the issue persists, we recommend that you uninstall and reinstall the AOL Desktop software. To learn more about uninstalling and reinstalling the AOL Desktop Software, please visit our help article AOL Desktop Software 9.7: Installing and Uninstalling.

Uninstalling the AOL Desktop software removes all damaged and non-repairable files. Once the uninstallation is complete, reinstalling a new copy of the AOL software is quick and easy. Please note that uninstalling the AOL software removes all screen names and settings associated with it. However, your Filing Cabinet files will automatically be stored on the desktop in a folder named Saved on AOL.

Important: If you have saved your AOL password on the AOL software, ensure that you remember your password before you uninstall the AOL software because uninstalling the software will delete your saved password. If you don’t remember your password, we recommend that you change your password before proceeding any further. You will also need to remember the answer to your Account Security Question (ASQ) to be able to change your password. You can change your ASQ if you don’t remember the answer to it. For instructions on how to change your password or ASQ, refer to the following online help articles:
