System Restore Points are all gone

I am running windows 7 64 bit home edition. System restore is not working. When I clicked on it, I had no restore points. When I create one manually, It says it created it, but then I close out and go back, and it is gone. Once today, it created one and kept it for an hour or so, but then it was gone. I have plenty of disc space, and have system restore turned on. I checked to see if the shadow copy boxes were checked in msconfig, and they were running. I unchecked them did a reboot, and rechecked them and rebooted, but that didn't work. I only have the one operating system, as I have read that is sometimes an issue.
Any help would be greatly appreciated.

Are you dual booting by any chance? That is one cause of no restore points.

No not dual booting. Just running windows 7

The single click download gave me a restore point, but then I closed out, and went to look and see if it was still there, and it was gone.

I am also finding that I cant use system backup. It fails, and when I look in events log, this is one of the many errors that are there.

Drew I ran into this in Oct and suspected the updates from MS. I was dual booting Vista and RC I assumed it had something to do with the dual boot. I never did find out what caused the change.

Trying to backup to a external Hard drive, which is E. I have a little flag down in my task bar telling to run backup, and when I do it fails. I got an error when trying to run that script file on the fouth link. This is an HP computer with vista 32 bit, upgraded to windows 7 64 bit. I also couldn't run system restore when I had Vista. I was hoping doing the install of windows 7 would fix it, but it didin't .
