After Pressing Join it loads up AC showing Laguna seca on the bottom right, and at the bottom left it says error can't compare checksum , The game then crashes Leaving a Red triangle with an exclamation mark(!) in it and the message Game crashed can't connect to remote server.
I have all the DLC,s and have all the dlc's (I purchased the ultimate edition key. I have also verified the files in steam.
Today I uninstalled everything, and reinstalled it. Still having the same problem. In CSP (about and updates), it says " AC is obsolete (v1.16.3 is required) I checked the changelog in AC files. It says I am on 1.16.4.
I reinstalled CSP and made sure that I was on .75 and I have 2 errors in red
It still says AC is obsolete. and now has added to errors Lua utilities in "extension/lua are missing (reinstall patch)". Done that but no change to errors , and still crashes due to checksum error.
I forgot to mention that I was trying to join Sir Spatts server. I am able to join other servers I have tried.
