Oops i meant 6.62 (typo). And nope it wasn't firewall or proxy because i don't have a firewall and i don't use proxy either. I guess whichever remote serve it was trying to connect to was down at that ...
It seems i can't license 6.64 it says i'm not connected to the internet, I have no trouble licensing 6.16 tho so it's not a proxy/firewall problem. Can someone help?
