This is the same old MS Access error we have been seeing for years... it's just presenting in a different way now... Reinstall MS Access 2010 in the Apps menu of Windows and it will work, you don't even have to close the Mitel app, just open the Apps & Features menu, find Microsoft Access 2010, select Modify, and then Reinstall and click through the prompts... takes like 10 seconds. Then you can just reconnect and the programmer will work fine.
Crappy answer, but it works consistently.
