Lab PC-1200 error code -10452 when accessing input channels

[JonJay]

I'm using a Lab PC-1200 card with LV 7.1. I have already done the fix with DAQ 6.9.3 and most of it works. In the Measurement & Automation Explorer the test panel works fine for the cards. But when I make a channel for the ACH0 input, the error code -10452 comes up and says: Error -10452 occured at AI Control. What does this mean and How can I fix it.

On the same note, I'm attempting to write a program that takes inputs from two PC-1200 cards. When running the program it works fine but then every one in a while it switches which port it inputs and outputs from. Can anyone help me?

Are you taking digital inputs?  What do you mean it "switches which port it inputs and outputs from"?

Please let me know your results.
