Error opening feature class- Number of shapes does not match the number of table...

Error opening feature class- Number of shapes does not match the number of table records.

I've been editing this shapefile for a couple of weeks on and off, it has 157.000 features. Yesterday when i was editing ArcMap crashed and now when i try and open the file i get this error. I realize that what probably happened is that a entry got added to the dbf table but the line didnt save which is why i'm getting this error. I need some advise on how to fix this. I know that you used to be able to use Microsoft access and Excel to edit the dbf but in 2013 they took away that option. Also i can't really download any third party software so i am limited in my options.

any help is appreciated,
Ben
