@Artificial. Something must have gone wrong when you modified it. You can try replacing it with my original gameinfo.txt file to see if that's the problem.
Tip: right-click and save link as file type "All Files (*.*)"
You can also try running the new SDK tools located in "common/team fortress2/bin" Just click on "hammer.bat". If you get any errors try running all the other bat files in that folder as well to insure everything is correctly setup.
If this is your first time logging in after the migration (Feb 8, 2022), you must reset your password to log in. Follow this guide if you're having trouble
