It was along time ago and for some reason when checking on my PM's that I saved or had gotten, found out that All of them were Gone!
Can't remember Who I talked to about it and checked now to see if I put up a Question about it, but I wasn't able to find one here!
What I remember about being told, was to check on my Settings here to make sure they all were in the proper setting condition and they All were!
Then the last thing I was told was it could have been a "Glitch" in the system??? But nobody knows!
I did Loose all of the PM's that I had saved at that time and Never got them back and it never happened to me again.
So all I can say is, it Happened to me too!
