I have 2 days worth of programming with Labview and sure enough, I am running into problems. I have Labview 7.1 and just purchased a I/0 card to do some data acquisition stuff. I am trying to acquire 2 analog inputs, 0-5 volt range, very simple. I am using the DAQ Assist thing to configure my inputs, one for each. Individually they worked fine, but when I have both of them running together, I got this annoying error message "Code 50103-specified resource is reserved". Please help.
