I have tried all previously posted suggestions to correct blank user interface with no success, including clean uninstall and reinstall (in safe mode), emptying "internet logs" folder, etc... Running Vista Home Premium edition SP1 on Dell XPS with Intel dual core 6600 processor. Other security programs include AVG antivirus and Adaware anti-spyware. Running ZA Free version 7.1.254.000. Appreciate any suggestions.
