We have multiple users, with different PCs all seeing this issue. Occasionally, DAQExpress will load but 90% of the time we are seeing freeze during the startup. All of the PCs were working with DAQExpress previously. It's seems like it could be DAQExpress trying to call NI and getting blocked, but we don't know how. Is anyone else seeing this issue or are there any suggestions on how to fix it? We have reinstalled DAQExpress and DAQmx.
