I just reinstalled my SC and whenever I join a game I don't download the map. Help me with this please. I'm sure I'm being a noob, but this was the most reliable place I knew to ask.

Maybe something with your firewall or Router?

maybe ur dl is invisible, it happens to me
or some ppl have to join and rejoin

It is most likely your router or firewall, as stated before. Port forward your router and turn off your firewall.

How many times have you tested it? It may of been coincidence as well.

Hmmm probably is your firewall, I'd advise reinstalling starcraft or restarting your computer if unableing your firewall does not work

Thank you ya'll. I think I finally got it to work again. It was a little bit of a fluke I think. Thank you for all your help.
