Materials and hdr are missing

After installing 1.5 I lost all materials. I looked at the firewall and kind find any restriction. Could you tell me what I should be looking in the firewall? Nothing lists under D5.

Hi sepo,

Did you check your network? Because our asset library is online.

Thank you very much

You mean if I have access to internet? I have access to internet. Not quite sure as there is nothing in the firewall that says exactly D5. Could you give me the hint what files I am supposed to be looking for.
