Moved to support.

DotA 2 is having an issue at the moment, more people are experiencing this.

Just wait and it'll get fixed sooner or later.

Not even competitive teams can play, talking about Virtus Pro against Team Liquid. (Watching Stream :P).

Thank you Hades, helpful as usual, they should promote you :D

Thanks, I just got promoted a month ago to Moderator :P.

I wish I could get more xD.

Anyway, just doing everything I can to improve the community :).

See Example:

Hey guys, I've found that whenever my Dota 2 Client has trouble opening I can verify the integrity of my game cache and it usually fixes it. You can do this by right-clicking Dota 2 in your Steam Library, Click Properties, Local Files and then click Verify Integrity of Game Cache.
If that fails you can also just delete the local game content and reinstall the game.

Rep'd for being a badass and for owning that scum lilpro.
