The HTTP connection failed! Are you sure you are connected to the internet?

As the title says, HB cant connect to internet for some reason. Altho im logged in to wow, and posting here so. How come this happens?
This is HB 2.0 BETA 10.

Also tried with HB 1 but i have the same problem with that and gets pretty much the same error message.

Someone know how to fix? I'd be glad for a solution This started about 1 day ago, mby 2. Thx

I'd check your firewall hasnt blocked it.

 

Good idea, altho it didn't work.

I see now that i get the same error message altho im writing wrong password. Not saying that my password is wrong, then i wouldnt have problem to connect so. Any other ideas anyone? Thanks alot altho for trying x)

 

I do not have an Proxy,
I've allways runned as admin,
No AV installed so, nopp,
Firewalls OFF,
Downloaded the newest version of HB2 again just in case.

So what else can there be?

 

Ok, ill try that, ill let you know how it went.

 

System restore never fails

The system Restore fixed it, Thread may be closed. Problem solved. Thx alot.
