Dear Barni,
on the Website from NI, I have found an very good link, which describe the "LabVIEW Internal Errors"
Take a look on the following Link:
http://digital.ni.com/public.nsf/websearch/01B186B5CEB1D07786256747000F4319?OpenDocument
Look, if the suggestions from the section "Specific suggestions for troubleshooting LabVIEW internal errors" help to fix the problem.
Best regards.
