I'm spending this weekend learning LTspice in preparation for my upcoming amp build, and I'm having an issue that may well be due to total ignorance. I downloaded the program, added several model files from Intact Sim City, read the manual, and then gave it a shot. I set up a simple circuit just to test everything out - figure 1. The issue is that whenever I try to run the sim, I get the error message in figure 2. I have tried several different triode models and get the same message; when I check the files they seem to have three connections, as does the schematic, yet the system tells me the schematic has more connections than the file. I also attached the triode_nh.txt file, which is in the lib/sub folder, and contains the triode strapped 6E5P model.

I'm stumped. I'm running Windows 7 Home Premium 64-bit if that matters.

Any help is greatly appreciated. I'm sure it's something stupid that I'm missing, but sometimes you just need someone else's eyes...
