Sorry, yes, it means upgrade. I'm upgrading from 6.XX version to the latest one. And my repository now is configured to autoselect, but if i configure it for hxxp://repository.eset.com/v1 we have the same problem.
We are upgrading all computers trough the HTTP Proxy. If we try to go to the URL: hxxp://repository.eset.com/v1 manually from any computer, works correctly.
