That was fixed in v2.5; you're using v2.4.
when i have the oldest version of zone builder i don't make maps when i have the latest version i die lol what i said
I tried the nodebuilder config, however it did not work. I decided to reinstall Zone Builder and it seems to be working for now.You probably mean ZenNode.exe. This is the nodebuilder for SRB2, which isn't just required for 3D mode but also to save your maps. It's definitely a problem with Norton, but since I don't use Norton myself, I can't help you with that. If you can't fix it, you can go to Tools -> Configurations, select the SRB2 configuration and then under the Nodebuilder tab set your nodebuilder to "ZDBSP - Normal (no reject)". That way you should at least be able to work on your maps again.
