You can look at the cncnetclient.log file found in your game directory and see what map it cannot render, then remove that map from your custom maps folder.
If stuck, upload your cncnetclient.log file to this topic and I'll help you further.
thanks. here is the log, I can't figure out what map it is
Hello,
The log points at these two maps: Try removing
Maps\Custom\d94192dda5c1219ffe9599307bcd61f348067c5f.map
Maps\Custom\Escape Velocity.map
I tried removing those files now from that folder but the same thing happens again. Do I have to remove the map completely from the main game folder as well? Cause it worked fine before with cncnet on one of the earlier updates. Attached the log after deleting those files now as well.
edit: I think I fixed it now by running cncnet as administrator
