The single inverted comma is not working. Whenever i press the relevant key, the double inverted comma is coming. I have been facing this problem for the last two months or so. Had a talk this evening between 7 and 7.15 with the support stuff, was guided over phone to logmein123. Could not run the applet after downloading the rescue applet.
My product number is1pm39pa#ac. The warranty period is still on.
