I'm using Gmax to try and learn ground-up mapmaking, and whenever I try to use Tool's structure command to make the scenario structure BSP, I get an error like this:

I've seen errors like this in other places, and they often have to do with file corruption. Is there something I've done wrong?

You have too many tags in your tags folder. Take ones you don't need out, run tool, put them back in.

That worked, thank you!
