The errors (pictured below) are related to COM components not being able to communicate with Aloha and often result in a terminal not able to process redemptions. When this occurs, please re-register Aloha.
In order to re-register Aloha, please run the following on the terminal:
%iberdir%\bin\Iberqs.exe /regserver
%iberdir%\bin\regsvr32.exe iberqsps.dll
