I found that my cookies file was corrupted but luckily I had a good one from my other computer and it solved my problems. I always keep a backup of my files in the profile directory but in this case I backed up a bad file before I knew it. I'll be much more careful in the future. Always good to keep backup files so if I had to go to the refresh option I could load my backup files and all settings would be restored. I also backup my computers once a week with a program from macrium.com called reflect. 20 minutes to completely back up your hard drive and about 5 minutes to restore it in case of a virus or a hard drive crash. Well worth the money and the customer support is fantastic. I would mark this as solved but I can't find a solved button to click on. Just an area to add a new message.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
