i am trying to use PS or any other vi from the NI elvismax palette and it blocks and i can't open it to configure the PS for example.
If you are not able to open the express VI, can you try:
1. removing it and then placing it again? (rule out that express VI is corrupt)
If you still can't configure it,
2. Could you create a new VI and add the express vi there to see if you can configure it? (Rule out that the VI is corrupt)
3. The driver might be corrupt. In this case, follow the Force Reinstall procedure.
Let us know if this helps you.
