Oops! You cannot open your shapefile and cannot repair using "Repair Geometry" tool. The specific error message says "Number of shapes does not match number of table records", and the steps listed in the official ESRI site does not help you. Also, the scripts for other tools cannot be found in the ArcScripts webpage. What to do???
It's not the end of the world yet, coz someone uploaded a 1999 year-old tool THAT STILL WORKS! Go to this support forum and download shapechk.zip found at the end of the page: https://geonet.esri.com/thread/177037#comment-614216
Good luck and breathe normally!
