Invalid Steam UserID Ticket

[Juan Deag 420 Blaze it]

Hello guys.

Since I've seen lots of threads regarding this issue I would suggest that you visit this Steam Support article: Invalid Steam UserID Ticket


This error previously included an issue with "An issue with your computer is blocking the VAC system. You cannot play on secure servers". These have since been seperated to provide a more accurate error message:

Messaggio originale di CS:GO Update 3/26/2014:

[MISC]
- Players that fail to properly validate with VAC will no longer get the generic "Invalid STEAM UserID Ticket" message and instead see "An issue with your computer is blocking the VAC system. You cannot play on secure servers."
