I have 2GB or RAM. I have over 150GB on 1 drive and over 90 GB on the other. I have tried to connect from my house and my office without success (I have it installed on my computer at home and my laptop). I performed the simple test and I received the message "Your test worked". I am not sharing the computers. This is not my first try with LV. I used it for over 2 years without problems. I started to have problems approximately 2 months ago. I do receive the brickwall in front of my blue world. As I stated, I have configured my firewalls and even disabled them without success. The only solution I have not tried is deleted my LV preferences. How do I do this in Vista. I have found the file, do I just delete it? What settings do I need to remember? Do I need to replace the file with something else? Thanks.
