I'm trying to join a .csv file with a shapefile in ArcGIS. In both the files theres a column named BlockID that are going to be joined the joined attribute between the two files. My problem is that when I do the join validaton it gets stuck at "counting the number of matchingrecords for the join" and after a while it says that the join is cancelled. I have done joins before, big ones like the one I'm doing this time, and never had this problem.
Does anyone know what might be the reason why the validation just cancels?
