eM Client not retrieving AOL email since update to version 9

AOL emails are no longer retreived since updating eM Client to version 9. I’ve deleted and readded my account several times. Only three emails have populated my inbox hours after adding the account again. Diagnostics indicate that the settings are okay and I have received messages in other email clients as well as online. This is running on a Windows 7 PC. Any ideas on things to investigate? Thanks.
