I was able to find the matching case by comparing your log file with others in that case. This specific error was fixed for LV 8.0, but there does not seem to be any information about a work around.
Looking on the forums, it seems that someone else was able to resolve this problem by reinstalling LabVIEW. Do you have another computer with LabVIEW 7.1?
