So, when i got on today, i was going to update Minecraft to 1.5.2, but when i try, i get this error up "Fatal error occured (4):null" i saw on the internet, that if you turned of your firewall, it would work, it didn't for me. I even tried running it in run as admin mode, and all that other stuff. Please if you know any other fix tell me! I'm running it on a windows 7 32 bit, i saw allot of people were having this problems on Mac, i don't know if it helps, but ok :P!

Something is blocking your connection.

What antivirus software are you using?

I think its Microsoft Security Essentials, i'm not quite sure. My computer is telling me that my Anti Virus software is that.

That shouldn't cause the issue. Do you either have McAfee or Avira installed?

Oh, yeah i have McAfee.

Disable it temporarily then attempt to login again. It is probably proxying/filtering the connection which is causing the fatal error.

I disabled it, it still didn't work, i even tried uninstalling it and then updating, then reinstalling it again, its still not working...

Never mind, i got past it, i told my friend to send me his 1.5.2 jar so i didn't have to update!
