Our IT person (son) may have updated when we weren't here - forgot to ask him - but for three days we've gotten red Xs and the messages "The server response for application update doesn't have the required structure," "One or more dependencies failed to be updated". Our current versions are: Blink 4.3.2; Rule version 1521; Anti Virus v. 1.0.697;Vulnerability scanner v.5.10.12 and Audits v. 2085. Can you help? Thanks!! Judith
