Hello, Which version of LabVIEW was the VI last opened and saved in? Here are some general suggestions for you to try to recover this VI:
<a href="http://digital.ni.com/public.nsf/websearch/01B186B5CEB1D07786256747000F4319?OpenDocument">LabVIEW Internal Errors (Failure in XXX.c / XXX.cpp at line YYY)</a> If after these you still cannot open the VI, please send a support request email to ni.com/ask with the VI.
