Verify integrity of your cach game folder under properties
Reinstall visual c++. Installation file is in steam/common/il2cliffsOfDover
If still no success keep verifying cach integrity.

Authentication error is fixed in latest beta patch , u have to install it manually. Ver 1.08 still have that issue, there is nothing u can do except installing newest beta.

This is good advise. The failed authentication is that Steam thinks you're still connected to an online server. Just wait a few minutes or restart your server.

Dragon, Your problem seems to be related to graphics issues, try to reinstall graphic drivers but before try to change ingame graphics settings, turn off trees or turn theme on if they off, the same with roads and the rest, try different resolution (should be native)... Authentication error is well known bug, sometimes u can wait ages to reset it, my mate advised me to start another steam game but it is not 100% working. Did u try previous beta patch?
