Hard to say. What's the actual error reported? It's the first time you get an error report? You never had success? Random errors? You made some big change to the code? This looks more food for NI's support than developers'. This kind of error should never happen, in principle. Actually it happened once to me but disappeared during the next attempt.

You should also tell us what you're actually trying to do or attach the VI you're trying to build. The PDA module has some bugs and this may be one of those bugs.
