MS pushed a Win7 update this morning while I had Labview open, but was not actually running any VI's. After that, several VI's that had been working yesterday, and have not been changed in any way hung when accessing my USB-6251 at the acquisition timing setup step, and after some time bombed. I also could not start the test interface in MAX but it did recognize the hardware. I noticed 2 listings for this hardware and on starting MAX and would first get an error message claiming the data base was corrupt (this box could be closed). I used the max reset feature to reset the data base. Now MAX features work ok and data transfer can be tested there and seems to work fine (in MAX). When I run my LV programs however, now they immediately bomb after the timing setup step when I attempt to simply read the sample clock rate using a property node (also has always worked before) with error 200478 claiming there are no channels in the task. Clearly there are; the program has not changed since yesterday when it worked fine. Obviously, the windows push corrupted something in the DAQmx arena. How do I clean this up? Thanks.
