DIO port config.vi : subVI is not executable

[fighter]

Hello,

Could you please help me in my problem explained below.

My problems is when I execute the VI file attached below, I get the error saying " SubVI 'DIO port config.vi': subVI is not executable". Same error for DIO port write.vi, DIO port read. vi.

I went to DIO port config.vi and executed it separtately which shows the error "Code Interface Node: Object code is not loaded".

Actually the program used to work fine and suddenly started showing this error which I could not resolve.

Below are my system specifications.

I have LV v4.0.1 running in my Windows 2000 OS.  I have LAB-PC+ DAQ card to control some motors. I also have PCI-GPIB card connected to Lecroy 8901 GPIB interface for data aquisition.

I have NI-DAQ 6.6, NI-VISA for windows 95/NT installed in my system.

I attached my program file with this message.

any valueble suggestions are greatly apprecited.

Thank you.

It sounds like your traditional DAQ driver got corrupted. Have you tried reinstalling it?

Thank you very much Dennis..

the problem is resolved after reinstalling the drivers.

Since I had limited knowledge with NI, I was hesitant to reinstall the drivers. So, I thought I would make sure with NI forums before doing that.

Now the program doesnt show any errors.

Just for information, why do the drivers get corrupted? I just want to make sure I dont do the mistake again if I did any.

I don't know what could have caused the corruption. You've got a very old version of LabVIEW (and unsupported on that OS, I believe) and a very old driver for the DAQ card.
