I found my problem. And you were right. It had nothing to do with LW. Instead my internet service. I had 5.8 version they offered an up grade to 6.1 Faster e-mail etc. So I down loaded it. When it was finished I restarted my computer as directed. Tried to log on and all I got over and over "was page not available". Ater 5 days of no real help my my provide I removed 6.1 and reinstall 5.8. Little did I know that the firewall from 5.8,6.1, & back to 5.8 All stayed active. I had 3 different versions of firewall fighting my computer. Deteled the first 2 and I works fine.
I still have my proble of defrag but I've learned to live with it. Defrag daily...You did explain what caued correpted files. That was important. You have been a great help. Ps My typing is not great. You may have typos. Thank Barb
