Hi DokTor
For some reason, your posted picture is not showing on my screen (I get a generic picture with domain unregistered), so I can't see the error that you are having.
However, judging from your thread title, I will try to help in the best possible way
This error usually happens when you change the location of your steam install (reinstalling steam to a different location, changing hard disk, reinstalling operating system...)
I see that you already tried to run CSGO at least once, and tried verifying game cache and refreshing SDK content; nothing worked you're saying.
What you can do is go to your CSGO folder, specifically \steamapps\common\Counter-Strike Global Offensive\bin and locate the file GameConfig.txt.
Open this file and make sure that the paths inside are pointing to your CSGO correct location (game directory, fgd,...) as, most probably, the error will be that the paths will be pointing to another location. Correct the paths manually if necessary. Save the file and try now to launch yor SDK.
Hope this helps
