Dota 2 Crashes - Corrupt files? Ongoing since mid summer.

[Phettstekt]

Dota 2 crashes alot, mostly after strategy time and the game is about to load.

I get the message:

Packed Sotre:: TestHashChunkFraction():Content filde d:\steam\steamapps\common\dota 2 beta\game\dota\pak01.vpk is corrupt. Verify integrity of game files.

Then when i try to start the game again. It's stuck on "downloading content" for about 10 min. Then it has to re-validate Dota 2. Takes about 30 min all and all.

I have tried deleting all the pak-files to re-download them.

I have tried reinstalling Dota2.

I have tried reinstalling Steam and Dota 2 to a different hard drive.

The problem still presists and it is super annoying to say the least. It causes abandons and irritations for everyone trying to play..

It happened to me few patches ago to.

I had to totaly unistal steam and use c cleaner to clean the register, than reinstal both dota and steam.

Never had issues after that.
