I loaded the shapefile and found some weird behaviour. I saw a line of points, with a break (presumably your 'hole') but the same as you, I couldn't click on any of them and they disappear. I cannot see the point numbers or any info. The table is blank. I can see from the properties that there are 2001 points but nothing else. I can see the coordinates of the points by right clicking. One problem that I have is that all my tooltips have disappeared. A small window opens but it is blank, so that doesn't help.
I could see the line in Google Earth but the points disappeared there also, if I zoomed in too much.
