How do you get that? I'm going to do that when I get home from work tonight
Add seta logfile "1" in the etconfig.cfg in your etmain\profiles\yourProfileName\ I would search the file for "logfile" first, to make sure that there is not a seta logfile "0" after your new entry, which would turn off the cvar again!
You can't start ET, so you can't do this the "normal way".
Every time that you start ET, it will create a new etconsole.log file in your etmain folder. It "deletes" the last version of the file and starts new one. Everything that appears in the console will be saved to that file, including all the carats in names, such as "^4d^5a^4n^5g^4e^5r". You can't open the file while ET is running, but you can copy and paste it and look at it as "etconsole - Copy.log". (in windows).
If your ET-startup fails, then the etconsole.log should end where ET is trying to load something or do something. You may want to save copies of the file after each time that you try to run ET, as that file will be re-written the next time you start ET.
I included a copy of my normal startup in that spoiler, just in case your etconsole.log just ends with a line like
and that is all
