NI might be able to. You can try contacting them by going to
NI Support. A corrupt llb when you don't have a current backup can be a major problem. That is why they should never be used in development to save your VIs. The intent of an llb was to give the use the ability to create VIs with longer names than the old dos 8.3 format. The only reason to use an llb now is to make distribution of a project simpler. Good luck.
