What device are you trying to simulate? [I'd be curious if my LabVIEW 2015 installation has the same problem]. As it happens, I'm writing some instructional material for a colleague who is having trouble doing what should be simple DAQ (low data rates), but she's using the Dreaded DAQ Assistant, which I am urging her to Banish. Getting rid of it and replacing it with real DAQmx code is quite simple -- do a Web search for the excellent NI White Paper "Learn 10 Functions in NI-DAQmx" and you will see that the basic steps are as follows (for most simple tasks):
- Open MAX and find your Device (or create a Simulated Device).
- Open Test Panels. Define the Task that you want to do (such as "Sample 4 channels, 1000 points at 1Khz, Continuously").
- Run the Task to be sure it does what you expect.
- Save the Task. Give it a better name than "My DAQ Task".
- Open LabVIEW, go to your Block Diagram.
- Drop down the following DAQmx Functions: Create Channels, Start, Read (or Write), Stop, and Clear, connecting them by their Task Wire and Error Line. Note that you might not need the first and the last function.
- Wire a Task constant to the upper left Task input of the first Function. Click the drop-down Arrow -- you should see your MAX Task appear. Select it.
- If you are sampling continuously, draw a While loop around the Read (or Write) function.
- In any case, do whatever you need to do with the Output (or Input) of the Read (or Write) function.
I realize this still doesn't answer "Why is MAX not working", but the answer may be as simple as "Bad Installation" or "Bad Device Specification". Tell us the device, we'll try it out, and perhaps can narrow down your problem.

P.S. -- oops, I replied without viewing your PNGs (I generally hate "pictures" on the Forums). Looks like you are using something called an SCC -- I'll check it out.
