Hello Msarikoc,
Is this the first time this is happening? Try unplugging your board and replugging it again on your PC, making sure its placed safely. Something else you can try is testing your board in another computer that has the NI-DAQ drivers and see if it gives the same error. If it does, then your board probably needs repair. If your board was working before, and this is the first time is happening, did you do anything different this time that could have possibly caused your board to stop working?
Please let me know about this.
Thanks,
LA
