Hello Jason,
You can try the following if you think it is suitable:
1. Run transaction ags_update and verify that the service content is using the latest download data. If all the lights are Green, then this is fine.
2. Check if is possible to reset the session in transaction DSA. Please run this transaction and enter the session number and click on display. Right click on the session number and then select the reset option.
3. If possible, create a new session and check if this is helpful. It may be that the current session is corrupt.
Regards,
Ruth
