I received an email saying that vers. 6 was avail. I tried to download, my firewall said there was a prob. but I ignored it as I thought I knew the program been installed. Download seemed to work then my desktop disappeared & screen went blank. Had to use restore point. Now LW won't work. Tried to reinstall. Does not recognise the only email address I have. Only purchased Jan/Feb this year. No contact for help. Any suggestions please? Thanks.
