Purchased minecraft.net. Worked for a while, then "Can't cnnect to Minecraft.net", also can't play offline. Just black screen. Completed list of fixes from cnet support icluding downloading Java 64 bit for our Windows 7 o/s also 64 bit. Any ideas? Thanks!

I would have a look at windows firewall if it is running, make sure it Minecraft.exe, ect has permission to pass throught it. and Net.

Also if you have your computer setup to the internet via a router.

Log in to it and check the firewall status on that.

As a rule of thumb never run two fire walls together.

Be it a hardware one, and a software one or two software fire walls.
It will cause you all sorts of head aches, when trying to connect to the internet, or setting a minecraft server up over your Pc and broadcasting it. Also check the port addresses the program uses to communicate over the net. You may have to open a port in your router if the computer is connected to that. so if you get stuck on it post back.

Did you install any mods, etc..
Try doing a force update to get a new folder.

You purchased minecraft.net? Wow, that must have been an expensive domain. How did you ever convince Notch to sell it to you?
