Hello - sorry to see this is happening. Could you upload the cncnet .log files found in your game directory? Could you also tell us if you have NET 3.5 and 4 installed?
find attached files, are these 2 the only ones u need? 3.5 and 4.6 .NET Are both enabled. the game never crashed when i first installed it, guy above suggest it was a custom map making it crash, these maps never crash in game, and i can minimise the crash box and still play...
client.log
