Uninstall and reinstall Labview, It will takes 20 mins depending of your computer and which toolkit and have addons you need... Only install what you need for your 24 hrs rush...All default parameter will be installed, And if the problem appears again, be sure that it is not provinding from Labview... In that cases, I would change my computer....
Note that I'd never use LV 6.1 ... I begin With LV 7.0, 7.1, 8.0 8.2 and now 8.5 ...
So maybe this is a feature that I can't know... Just consider it before uninstall...
Hope you finnish in time...
