License File Not Working for KickStart

I have downloaded and installed a license file to use the DMM feature on the DAQ6510, but when I go to use the feature and record data, I am still met with the "Install license" message. When I go to re-install the file, I receive the message: "License file has already been entered. Error=0". Unable to check the license back in.

Hello,
I apologize for the delay in response on your post.
This will require further investigation on an individual basis, which would be better handled with a support case here:

However, there may have been a malfunction when the license installed.
Our support team should be able to help you more effectively in resetting the license and Host ID of your installation.
