TNG not detecting buffer after installation

[Belinda Frick]

OVERVIEW
When installing TNG, the system will search and detect the TNG buffer automatically.
This may take a while. As soon as this process is completed TNG will start logging calls.

If the buffer was not detected, you will see a red flashing icon with a warning message,
Invalid buffer or Buffer not found.

Please follow these steps: Option one
Close TNG
Click on Start -> Control panel -> Administrative tools -> Services
Stop the TNG service (wait a few min)
Start the TNG service
Open TNG
Option two:
Delete the "Datatex" folder
PS: All user details will be deleted when deleting the Datatex folder.
Make a backup of the "data" folder (C:\Program Files\Datatex\tng) to avoid loosing usernames.
Uninstall TNG
Click on Start -> Control panel -> Add or Remove programs and remove TNG
Re-install TNG from the cd
You should now be able to log on to TNG and the system will detect the buffer.
