MAX Database Corruption
In rare cases, it can happen that when starting the “NI MAX” a popup like in the screenshot below is displayed.
The refereed knowledge base article says the following about the cause of this problem: “NI MAX Database corruptions are rare, but may be caused when a system reboots without being properly shut down due to a power loss or a system crash.”
Reset the MAX database. From the KB article: From within NI MAX, select Tools » Reset Configuration Data. Confirm the warning dialog with “Yes”.
Reconfigure all needed device (especially the device names) DAQmx tasks.
The following errors can indicate a problem with the MAX database. Check the MAX if one of these errors occur.
Application hangs during “Discover hardware” (or MAX doesn't start anymore)
